Ensuring launcher is up to date Fetching origin fatal: unable to access 'https://github.com/discourse/discourse_docker.git/': Could not resolve host : github.com error: Could not fetch origin Launcher is up-to-date And also curl https://github.com/ doesn’t work

Hey Anna! Sorry you’re having trouble. Either github is down, or, more likely, you have a dns or networking problem.

I found some solutions in discourse community but none of them solve my problem. Maybe I should change my nameserver in resolv.conf but I have no idea this is right or wrong nameserver address. nameserver 127.0.0.53 options edns0 trust-ad nameserver 8.8.8.8 nameserver 8.8.4.4 Thanks a lot

It’s not a Discourse problem, so this isn’t the best place to look for a solution. If you’re going to use the Google name servers then you should remove the other one. Also, in many configurations, Linux will overwrite resolve.conf, so if changing name servers fixes the problem you’ll still need to…

[image] So you mean I might remove nameserver 127.0.0.53?

Should I do something after change nameserver in resolv.conf like rerun docker?

You can try the curl command and see if it works, and if it does, you can try to ./launcher rebuild app

I looked at my test server and found it has like this nameserver 127.0.0.53 options edns0 trust-ad So I followed that but still not working. My thought is I changed /etc/ssh/sshd_config file to use ssh remote from my local PC Changed like PasswordAuthentication no -> PasswordAuthentication yes …

Really have no idea why my server has this problem. I didn’t really do anything. My community was running fine, but all of a sudden this happened to me and I couldn’t connect to my website

[imagen] annakein: So I followed that but still not working Sometimes the local dns server gets broken. Replace that with 8.8.8.8 and see if that fixes it. Have you rebooted lately? Maybe it’s in adding limbo upgrade state.

No creo que Discourse-doctor sea de ayuda aquí. Es un problema del sistema operativo.

Actualizar y reiniciar es una buena idea.
