Hi! My site suddenly “disappeared” after my web host updated and restarted my server. After some poking around, I did a ‘netstat’ and only ‘tcp6’ entries were listed for the ports that discourse were supposed to serve (and probably is serving). This is a problem for a few reasons. I can’t displ…

I don’t know how the launcher application works, so how do I debug this issue? It’s obvious that github.com is actually resolvable from my machine, and that was my only lead.

The launcher application is starting a Docker container and then running the commands in the templates from inside. Do you have some special DNS setup on your VPS that isn’t getting auto-configured?

I found a solution in this thread here . I looked up my DNS servers in resolv.conf, and put that in the configuration file for docker. I don’t know why docker doesn’t use the same dns as the rest of the system by default? What am I not understanding here?

Hmm… the rebuild worked, and the site went back up. I don’t know why netstat only displays ‘tcp6’ ports… because I don’t think that’s what I’m browsing right now. I’m confused.
