connection has timed out - email from Samsung phone

Samsung Galaxy S10 default web browser used for years to read Comcast emails.
Started getting connection has timed out errors a few/several weeks ago.  Could

not get it working no matter how many timed I "retried".
Also, noticed accessing email using Google Chrome "on my desktop" also started

to occasionally return the timeout error but would get through on the "retry".
Again, on the phone it now always times out and never gets through.

Given that both problems on a separate android phone and MSFT windows workstation started recently I'd be surprised if they weren't related and something on xfinity's side has changed.  Has the network responsiveness on the comcast side simple slowed a bit such that my phone always times out and my workstation about 25% of the time times outs?

I did just discover today that if I don't use the default browser for the phone(Samsung Internet) and use Chrome on the phone I was able to use email on the phone.  Yes, it is
a work around but why has this started happening to the service I've used for years?
