Unable to login using mobile app after latest server update

I noticed last night that neither my phone or my wife’s phone which are both configured to connect to my home assistant server via Nabu Casa are able to connnect. i can still connect locally using the local iP:8123, but I can not connect using Nabu Casa connection. I have verified that my Nabu Casa connection is active and connected and logged in. I"ve tried using the actual URL from the Nabu Casa config page and also connect using Nabu Casa toggle switch. Neither will work. Can someone give me some things to check to see why I am no longer able to connect? Seems that it was working fine till the latest app update.

Thank you in advance for your assistance!
