I triggered a rebuild but this is what I got:

```plaintext
I, [2023-04-07T19:17:58.707365 #1] INFO -- : > cd /var/www/discourse && gem install bundler --conservative -v $(awk '/BUNDLED WITH/ { getline; gsub(/ /,""); print $0 }' Gemfile.lock)
ERROR: Could not find a valid gem 'bundler' (= 2.3.4), here is why:
          Unable to download data from https://rubygems.org/ - Net::OpenTimeout: execution expired (https://rubygems.org/specs.4.8.gz)

```

However I can curl [rubygems.org](http://rubygems.org) from host.
