Can't Add an Account and log in

[David Brooks]

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."

same issue without changing anything to the repo though.
can't connect to github credentials

Authentication failed
Failed to check login for user [XXX]
Requires authentication

 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.

    https://dev.azure.com/wwww/xxxx/yyyy/zzzz

    https://wwww@dev.azure.com/wwww/xxxx/yyyy/zzzz

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

This is ocurring to me too. Same issue
