My.tablotv.com won't find my Legacy tablo

This morning when I tried to log into my.tablotv.com with Firefox, it claimed there was no Tablo to be found.
It’s there using Roku, Android Tablet, and the Windows app, but when I try Firefox this is what I get:


I tried Chrome but after jumping through all the hoops to get it to use http:// instead of https://, all it does is spin.
Even though it only happens with the browser connection, I tried all the usual steps of rebooting, etc. Nothing helps.
Anybody else having problems?

Mozilla Firefox v129.0.2, and Google Chrome v1128.0.6613.120 work.
MS Edge v128.0.2739.54 hangs at connecting.

Try Firefox in a private (a.k.a. incognito) window.
If it works, there’s a problem with cookies, and you could delete browser cache.

Yep, that worked.
Thanks
