Thank you very much for that detailed answer.
I was facing two issues, that had nothing to do with each other:
- One of the network service providers of the Linode Datacenter was having trouble this morning, that was the problem with the rebuilding and the git pull commands.
- I administrate the app for a non-profit organisation. They commissioned a domain transfer a week ago. I didn’t know, that the transfer was happening this morning, but it did
And due to that, there was a certificate of the new domain name registrar which got into the way. It’s still not solved, because I don’t have the login information for the domain-configuration yet, but I’m pretty sure it has nothing to do with discourse.
Thank you all very much. I like this viral community on meta.discourse.org a lot
