Can't Add an Account and log in

Question

I erased the repo from my local drive to do a virgin build of code from the repo. I was then unable to clone the repo because I could not log into my account. I was told to upgrade from 3.3x.x to 3.4.4.0. I did, but still could not log in. I deleted my account to start over, including obtaining a new PAT and I still cannot log in. I found the following thread on your support page, which is my exact problem, but no answer was provided: Page not found error in Remote Repo connection with PAT in Azure DevOps.

When I click Refresh Personal Access Token and enter my credentials, I get:

"Authentication Failed

Failed to check login for user

Page not found."

to add to David's info.
host URL was like https://mycompany.visualstudio.com

user name was case sensitive email on the visual studio account so like SmithXY@mycompany.com

the password was the PAT token

I have the same problem when I want to connect it to my GitHub, and it is the first time I use it, but the password even though I have changed it thinking that it could be that it has not worked for me, I still get Authentication error.

I found the problem.

When creating or authenticating an existing account in SourceTree, SourceTree wants the URL specified on the PAT creation screen, not the so-called full URL.

Hosting Service: Azure DevOps

Host URL: as describe in first above

Preferred Protocol: HTTPS

Authentication: Personal Access Token

Also, in my case, when trying to clone the repo, the full URL was given to me two ways. Only the first one worked.
