please attach full logs zip file.
But ensure first you do have debug logging enabled beforehand - see https://support.plex.tv/articles/201643703-reporting-issues-with-plex-media-server/
To get fresh diagnostics, after ensuring debug is enabled on the server, restart the server. Go through setup and when appears to be stuck, wait 5 minutes just to make sure it is not just slow - and then capture a screenshot (do not crop as i need to see the time and url as well) and download the logs zip and attach
