Trying to resolve my [Patreon problem](https://meta.discourse.org/t/trouble-with-patreon-on-multisite/118102) I’m doing a rebuild. I have only official plugins, and it’s failing with
```plaintext
I, [2019-05-19T22:35:13.979327 #15] INFO -- : > cd /var/www/discourse && gem update bundler
ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
timed out (https://rubygems.org/specs.4.8.gz)
I, [2019-05-19T22:36:14.620134 #15] INFO -- :
```
I’m sorta stumped.

I also encountered the same problem.

Thanks, but I’m on `tests-passed`.

If you’ve upgraded to tests-passed you also can’t swap back to beta until beta catches up.

It can’t hurt to disable official plugins too, just to troubleshoot.

Good idea, but no joy. I removed all plugins, and it’s still failing with
```plaintext
I, [2019-05-19T23:53:44.891357 #14] INFO -- : > cd /var/www/discourse && gem update bundler
ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
```
I tried upgrading Docker and disabling IPv6. Still no joy.

Ok, and if you `ping www.google.com` does it resolve?
What result do you get if you `nslookup` ? Does the connection to DNS time out?

Well, in the existing container, I can curl `https://rubygems.org/specs.4.8.gz` without any problem.
I guess I’ll next see if I can crank up the latest discourse/base image and see what it’s doing.

Well, a while back I enabled ipv6, and something with that broke some stuff (but only some?) inside Docker containers. I turned off those IPv6 addresses and it seems that this and my other problem are resolved.
