@XfinityBillie​  I am having the same problem:  here is the message:

Access Denied

You don't have permission to access "http://login.xfinity.com/login" on this server.

[Edited: "Personal Information"]

[Edited: "Invalid Link"]

I am just using my regular login -- I am able to access my email on on phone.  this is the message I get when  I try to access my email through my computer.

Good afternoon @user_slqe8m, and thank you for reaching out on our Community Forums today to let us know that you are also having this problem and receiving access denied error, we appreciate your time and assure you that our team is here to help. We'd be happy to help troubleshoot your email issues. Is it ok if we ask a few troubleshooting questions?

I see that you stated you can access your email on your phone but receive this message on your computer. To confirm, are you accessing your email through the XFINITY website or a third party client server such as Outlook for example?

@user_slqe8m​ 

Have you tried a different browser besides Edge?

I'm using Chrome as the browser.

@XfinityAlyssaA​  -- I am trying to access through Xfinity website and Chrome is my browser.

Hi there, user_wix137Thank you for all the steps you took to try and resolve the error you see when trying to access your email box. Narrowing down to Safari and just the MacBook laptop is very helpful. Is your browser also up to date? Did you try in Private Browsing?

Yes, my browser is always up to date as well as my OS. I have tried Private Browsing several times, all to no avail.

@XfinityMartyR​ Comments on the "Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server." issue. I have tried many methods to login using Windows 7 and Windows 10 computers that are hooked up to the internet direct to the modem, on my wifi router, and using my Apple I phone hot spot - different browsers (Firefox Opera Pale Moon Vivaldi Edge)  and both current and old versions of the browsers. My results are that 95% of the time the "Access Denied .." error occurs but sometimes the login works (or I could not be posting this reply since I do not login using my phone (screen to small). The 5% that work follow no pattern every combination has worked at least once. I have run 100+ tests using 3 computers and changing the internet access method and browsers on each. Hope this helps - this problem started several days ago.    

@user_1loirn​ nope I cannot explain. Perhaps find a real email service that prioritizes email. My email returned to normal a couple of days ago….you know, once I finally switched to iCloud Mail with Apple. I am slowly severing the Xfinity connection. 

@user_1loirn Hello and good evening. Thanks for posting and sharing your experience with the community. We appreciate it and that you thought of us to assist. We know how important the email access is, and want you to know that we will work together to ensure you get into your account again. I rely on my email for access to all my services, so I know it is vital. I hope you are doing well this evening. How are you, did you have any big plans for the weekend? How are you accessing your email? 

I am

posting this via my iPhone. Can access email on my phone only. High level tech support from Xfinity tell me they know about this and are working HARD to fix the problem. I think that is just the company line. They say there is an outage but when I check on Xfinity outages , there are none. 

Reached level 4 security saying they know there’s an outage and they do not know when it will be fixed. I can access my Xfinity Comcast’s email on my phone. I can log into Xfinity on my phone. They had me restart modem clear caches change browsers but nothing worked .

Greetings, @user_v3jvwk! I hope your week has been treating you well. Thanks so much for taking a moment out of your busy day to leave a post on our community forum. I'm sorry to hear you're having issues accessing your email, but you have definitely come to the right place for assistance.

Have you tried logging in using a Chrome incognito browser window (Ctrl+Shift+N on a PC . . . ⌘+Shift+N on a Mac)? This temporary workaround has been successful for some customers experiencing this server permission issue.

Hello,

Yes, I tried this and recieve the same result. 

@user_v3jvwk​ 

Try turning off your extensions.

Thank you for responding, @user_v3jvwk. If you could send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account, I'd be more than happy to look into this for you.

To send a Direct Message, please click on the “Direct Message” icon in the top-right corner of the screen, next to the bell icon, click the "New message" (pencil and paper) icon, then type or select "Xfinity Support". Type your message in the text area near the bottom of the window and press Enter to send your message and initiate a live session.

@XfinityJamesC​  I posted the reply below several days ago .... since then I have reduced my "Access Denied" rate to less than 10% by using my Windows 7 computer running Firefox 115.14esr, connecting directly to the modem, and always starting from the xfinity overview screen to start my login. I cannot explain why this works 90+%.  Also to update my original comment below I also cleared all cookies, restarted my modem/router, turned firewall on/off, used VPN, and tried private browsing sessions.

One last note is that the error is not a time out server access error since it happens immediately and my solution above is for information only and does not the problem.

Hey, user_ock7da! Thanks for letting us know about the issues you are having. By chance have you tried to access it using the Private mode on Opera?

@user_ock7da​ My previous post show that in testing different combinations of browsers(private and non-private sessions) - windows versions - connections(wifi, direct cable, phone hot spot) - clearing/saving cookies - firewall on/off - vpn ;  that at any time some combination will work and then fail the next time. My guess is that in mid August Xfinity made a security change to the pathways that access the infinity.com sites and that change is the problem since our login attempt is being  flagged as a threat and then access is being denied.  So until Xfinity fixes this security change problem that trying to find combinations that attempt to bypass this error cannot be a permanent solution since they may fail the next time - Note my Firefox method failed after a week and I am now using Midori browser method to make this post.

@user_w0a9yi might be onto something. I was up and running for a week (after 2 weeks of Access Denied). I cleaned-up the laptop last night (cookies, caches, back-up) and now have no normal access to e-mail or Comcast. 

Private mode does NOT make any difference, it is still happening. 

Hey there, @user_40p1st. You mentioned you reset your password inside the Xfinity app, were you able to update the new password on your iOS device email app? 

I was able to update the passwords as far as I know.  Neither my ipad, my phone, or Outlook on my laptop are able to send emails, although I am receiving them.  Have the settings changed?  I have checked the box on security allowing 3rd party apps, but the boxes keep popping up for the correct name and password on the IOS apparatuses, and my Comcast Outlook emails (including work, home, 2 businesses-100s of emails) have been lost in trying to correct the accounts.

I know Xfinity is no longer supporting new emails, but if this is the way you are trying to get the public to stop using your service you could have sent an email yourselves.  This is a very low way to get rid of us.

@user_40p1st Thank you for confirming the steps you have already tried. Just to clarify, on the iPhone and iPad are you trying to use it with Apple Mail? You also mentioned Outlook, are you getting the same error there? Also, to confirm, you are able to log into the Xfinity webmail via our site and see all your emails?

Hey, grammie8! Thanks for reaching out to us on the forums! I apologize to hear that you are also having this email issue on your Android phone. Can you let us know if you are trying to get your email through a browser on the phone or is it through a 3rd party app like Outlook?

Yeah, be careful.  I allowed the built-in tool in Outlook to try to repair it, and lost 100s of emails.

We have 2 business ones, and 2 personal ones.  None are working well.  I will be switching to gmail if we have to login to xfinity to do email-it is not efficient on a cell or ipad, even Outlook is not working.

Thank you for reaching out to us @JimNBeck! Are you able to access your comcast email through our site here on other devices?

Well, no. But I think that is an issue with the Xfinity website.
I've been using a Firefox bookmark: https://login.xfinity.com/login?c_ds_na=c_ds_na%252Cc_ds_no%252Cc_ds_t...  I did not copy/paste the whole URL, but it works. I've been relying on it since I got my new laptop a few days ago. I can access my email via Xfinity on my Galaxy G20 too.
If it helps I could post images of all the steps I'm going through up to the error.
I'm new to and using Eset Internet Security.

@JimNBeck, Can I have you check out How To Set Up Your Xfinity Email Address With an Email Program and see if that helps. 

I, too have the same problem.  It seems like everyone has tried everything.  I'm ready to think it is more of an Xfinity glitch and not the 10 other things I have counted that people before me have tried to no avail.  A copy and paste of an earlier conversation reads as follows:

XfinityMartyR  Official Employee 

In my Google settings, under Privacy and security, then under "Site settings", then "View permissions and data stored across sites":  I always leave Xfinity.com there.  It has the black and white X, the Xfinity brand logo and when I click on it to expand it, all of these in the drop-down, including connect.xfinity.com (with 9 cookies) have the official logo.  However, there is one that has a world globe:  connect-ucs.xfinity.com (with 1 cookie).  If I could get an Official Xfinity Employee to answer the following questions for me:  1.  2.  What are the differences between the two?  3.  Why two connects?  4.  Does this have anything to do with our log-in problem??  5.  A user above mentioned the following statement. I would like to know if there is any truth to this:  "My guess is that in mid August Xfinity made a security change to the pathways that access the infinity.com sites and that change is the problem since our login attempt is being  flagged as a threat and then access is being denied."  Thank you.

Hi there, @user_b6amtq! While we don't have the capacity to answer questions on Google's storage and management of cookies, I can say that there are multiple levels of security involved. The login issue is something that is still being worked on, and we hope to have it resolved soon. There should be no need to change or update anything on your end once it's resolved, but if there is, that information will be posted. Fortunately, there are a plethora of ways to retrieve your email beyond this method. Are you able to get your email?
