Hi @heuy59
welcome to the forum! Please introduce yourself here!

do you get that error when you open the link or after entering your username/password? Because I can open it and see the login screen.

I get the error after entering my username/password for the first time. Afterward, i am not able to even see the login screen unless i open a different internet browser. Hope this explanation helps to find a solution for me.
