Having the same issue here. Did anyone managed to fix it?

Same problem here. We solved it by downgrading to 14.7. But we weren't able to set it up anyways😂

After the setup we are ending at the same page. Our proxy log shows, that XCode Cloud is trying to access this url: [servername]/api/v4/projects/[group]/[project_name]/. But this must be incorrect API path, because you can only access if you go to this url: [servername]/api/v4/projects/[project-id]. Does anyone have the same or similar problem?
