Temporarily blacklisted IP

I have been unable to get my Comcast email with the Apple Mail app on my MacBook, iPhone and iPad. When I click on the account, I get a message - "Temporarily Blacklisted IP Address-Try Again Later."

The problem started yesterday and is still continuing. I did not make any changes on my devices. I haven't done anything else that would have affected the IP address. I'm in the same location as usual, trying to log in the same way as always. 

Everything else is working fine.

1.  I can access my Comcast email on connect.xfinity.com on all three devices (Mac, iPhone and iPad). The problem is only when using Apple Mail.

2. In the Xfinity email settings, the third party access security checkbox is on.

3. I can get email from my other accounts using Apple Mail.

4. My internet is working fine. I reset the router to see and the Comcast issue is still there.

4. I've made sure that the user name and password on the Comcast accounts is correct. I've checked it multiple times.

I have not experienced this "temporarily blacklisted IP" issue before.  

I'd appreciate any suggestions. Thanks.

As a followup, I set up a VPN so I can have a new public IP address. For a few minutes Apple Mail was able to retrieve emails from Comcast and then the problem reoccurred, showing that the IP address was temporarily blacklisted.

Could someone at Xfinity request me to send a direct message so I can pass along the blocked IP address and see if the issue can be resolved? Thanks.

Had the same issue; could not get incoming emails in Microsoft Outlook or Apple Mail, but emails were processing fine on xFinity.com. Issue was WiFi router was hacked. Solution was to reset router to factory settings and all has worked fine since.
