We run a discourse at discourse.lubuntu.me. It is configured to have that as its base URL.
However, internally, the system is getting 500 errors with its internal certificate.svg links and the discobot builtin for greeting users.
SocketError (Failed to open TCP connection to discourse.lubuntu.me:443 (getaddrinfo: Name or service not known)) /usr/local/lib/ruby/2.6.0/net/http.rb:949:in `rescue in block in connect'
This is behaving like it’s unable to do a DNS lookup inside the container running Discourse. Is there a way to fix this issue or better debug it?
