Strange Webmail problem

Having a problem logging into my AT&T web mail account on Manjaro. It’s not liking my userid/password. But this same userid/password works on Mint. This problem seemed familiar to me. I think I had a similar problem a few years ago. I could successfully log into my Webmail [remotely] in Miami but it failed locally. I don’t remember the resolution. I think I assumed a routing problem. However it can’t be a routing problem because this is using the computer at the same location just dual booted to a different Linux distro.
