If the URL contains "live.com" , I get the "Something Went Wrong..." message. I can use other non-live URLs to log in to MS locations such as my MS account, but the presence of live.com stops me with the message.

Does someone know what live.com is about? Is it looking for some sort of verification. I am in the Insider program, but the problem URLs seem more oriented to my credentials or authorization in general. My MS account credentials seem to be fine.
Thanks for any ideas.
