Hi,

what authorisations credentials are you using? For GitHub you need to provide your user name and a Personal Access Token (use this as password) for the repository in Archi. You can enter this by selecting the repository in the Collaboration Workspace and then in the Properties window, Authentication tab.

I'm use credential for GitHub - username (2024AjaxArchi) and Password.
Apply it in Archi -> Preferences -> Collaboration
In Global User Details: Name for GitHub
In Authentication: Password for GitHub

When I start "Add remote model ..." I insert path and the same credential for Git and I get the error response below.

What do you mean Phil by "Personal Access Token"?
How can І get it?

[Phil Beauvoir]

You don't use your GitHub personal password, you must create a PAT and use that. See:

https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens

Thanks Phil.
So I need to create a SHH token or something else?
And configure Archi to use this token?

Thanks Phil.

Not for https connections. You need to create a new PAT and use that. Please read https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens

You need to create a new PAT

Thanks so much Phil for your help.
I generated the PAT as you suggested and successfully completed the first synchronization.
