Starting on November 21, gmailify is not able to connect to my Comcast account to retrieve my messages to gmail

So I'm betting on a potential issue with situation we're all in right now - given the recent issues from Password leaks experienced by Xfinity/Comcast, people have been forced to not only change their passwords but also enable OTP for MFA.

My theory right now is that the issue is: Gmailfy is doing its thing like it always does but now we're to get an OTP sent to us and it's not being invoked.  So an additional security standard, which is a good thing, is bricking the process from outside sources.  This is just a guess though as I started getting this about 48-72 hours ago for my own account, which is quite frustrating.

I would think a solution from Xfinity is to implement some form of security check for external parties, ask the user to authenticate via an OTP, and then allow the authorized access to continue.  Should the password change and a user has to re-auth, then this would need to occur again but only this time.

But again - this is a theory and hopefully this is resolved immediately.

@Xfinity_Support 

If it was only me doing something wrong (incorrect password for example), then how come we have so many users also seeing the same problem?  It is not helpful to say "Have you tried to reset your Gmail password and then try again?" or "Can you tell us more about the issues you're facing along with any error messages?" or "Are you able to successfully access your Xfinity Email by visiting our Xfinity Email Web portal?" to name a few.

Those are inane answers that show that you have not read the whole problem description or understand what it means when another user says "I AM HAVING THE SAME PROBLEM AND SYMPTOMS" (they have ACTUALLY read the description and are seeing the same behavior).  And what is the use of saying that you can read your e-mails through the xfinity email webpage!  We are not complaining about not able to read xfinity emails.  We are complaining that we cannot get the emails out of xfinity INTO gmail, like we used to be able to do until this problem started.

So again, I ask, what are YOU REALLY going to do?  

Can this be escalated?  How many users you need to be complaining about the problem so that this is escalated?

I am having the exact same issue as every user in this thread, and I don't see any actually helpful responses from Xfinity.  I followed all instructions, unlinking my email, changing the password, verifying the Third Party Access Security is ON, relinking to Gmail, and nothing is working for me or my husband.  The error messages I receive when trying to relink indicate Xfinity is NOT communicating properly with Gmail.  When I use Gmailify, the password isn't accepted.  When I use POP3, I receive "Server denied POP3 access for the given username and password" with NO SSL, and when I try to use the secure connection (SSL), the error message says, There was a problem connecting to mail.comcast.net
Server returned error: "SSL protocol error. Please try disabling SSL, or contact your other provider to verify the correct port settings."

This does NOT sound like a Gmail problem!  

Please help.

Following - Same exact issue here too. It started happening a few days ago.

Yesterday I asked: How many users you need to be complaining about the problem so that this is escalated?

To which I did not get a reply.

17 different users are running into this problem... How many are needed to escalate the problem?

I'm having the exact same issue. It's been at least 2 weeks. From my past experience with Xfinity, it's very difficult to get in touch with the smart people in tech support. It takes many phone calls, many disconnected calls and lots of time on hold until the issue gets escalated to the right team. 

I'm not too hopeful for a quick fix, but I'm just throwing a comment here to add to the list of people that are having the problem.

Yup, me too. tried all the "fixes" but nothing working. I will give it a week and then it looks like I get a shiny new email address and get to spend hours changing all my linked accounts using the current email. Maybe I should have done it years ago- Thanks Xfinity for giving me the strength to finally make the switch

I am also having this issue. I've changed my password and confirmed I'm using the same password I would use for the web UI for gmailify, but it acts like it's the wrong password.

I am 100% sure this is an issue in Comcast's side. With the choice to kill the Xfinity email mobile app, we should at the very least be able to check our email in a way that makes sense. So much of people's digital presence and life are tied to email addresses. I would gladly migrate my email off of the Xfinity service if I could at this point, but too much stuff is tied to it.

I swapped my Gmail over to POP3 access and it seems to be working OK now.

I had same issues. I setup auto forward in xfinity email settings to the desired gmail account. Kept the "sending email as" setup in gmail. Deleted receiving comcast email setups in gmail. Now, I am able to send a comcast email from gmail and it retreives it instantly. You can make new gmail email addresses to forward to if you want to segregate the mails.

I am having the same problem with Gmailify. Same user name and password do not match error message. Please Comcast, stop providing stock suggestions that do not resolve the problem. There is a specific issue between Gmailify and Comcast causing this problem. I tried using the Thunderbird email app on my phone, which has a set up button for Comcast, and my password was accepted. So now I can at least see my Comcast email on my phone. But since Comcast has no native email app of its own, it is absolutely essential that it work with ALL mobile apps. If Comcast customers cannot connect their email to Gmail, you Comcast have a BIG problem on your hands. Please get this fixed!

I am also having the same issue. Tried unlinking my Xfinity and re-linking but it keeps saying email and password do not match. When will this be fixed.

I have been changing ALL my emails from Comcast.net to gmail.com for years ... I think I have everything that is important moved over.

I am going to change my home ISP from Comcast to ANYBODY because of this issue.

I was able to get it working again, at least for the last 24 hours anyway. I disabled MFA on Xfinity, unlinked in Gmail (this took a while to process for some reason), then removed in Gmail. Once that completed, I Added as new, used my same dang password that wasn’t working, then once the mail synced a few times, I re-enabled MFA on Xfinity and it’s been syncing fine ever since.

this definitely points to an Xfinity and MFA issue even with the checkbox for 3rd party mail enabled. Hope this helps others.

I have the same issue. Suddenly, the gmail app on my Samsung GS24+ gives me the same error message about an authentication error with my user name and password not matching.  I haven't changed any settings or logged out from either gmail or my comcast email on my phone.  Please advise how to fix this.  Thank you.
