My website suddenly have issue with connectivity. I think it’s docker related and I want to know what command I need to use to upgrade it. update: I updated discourse but get ssl issues. Tried renew letsencrypt, in the logs I see > “\_error\_level=‘1’” > “\_set\_level=‘2’” > “The NOTIFY\_HOOK is empty, just return.” Probably due to move to ZeroSSL. I run git pull and I get: > "Unable to access ‘[https://github.com/discourse/discourse\_docket.git/](https://github.com/discourse/discourse_docket.git/)’: Could not resolve host: [github.com](http://github.com). I tried to upgrade docker and the command doesn’t do anything: > “wget -qO- [https://get.docker.com/](https://get.docker.com/) | sh” I don’t know what to do, many issues and site is down because of that. ---

That mean your server can’t reach GitHub. That will break the update process indeed.
