Getting IPAddr::InvalidAddressError on valid domain look-ups

[melroy89]

Hi,

I create an issue here, since I believe it's a bug in Ruby and not in Mastodon (v4.3.1).

I'm getting IPAddr::InvalidAddressError errors on valid valid requests / domains. I have IPv6 disabled.

And yes, the DNS server returns a valid response on the server as well as within the docker container. To confirm it's not an issue with the network, I executed a simple curl request. Eor example (on the VM as well as in the docker containers):

curl https://mstdn.social/.well-known/webfinger?resource=acct:BrodieOnLinux@mstdn.social

All works fine! IP address gets resolved and I see JSON content. No problems.

However, within the same Docker container Ruby is used for running Mastodon, and I get:

Mastodon ticket: mastodon/mastodon#32792

Ruby version:

Referring to the following comment in the Mastodon issue, it appears that this problem is specific to Mastodon (not the ipaddr gem).
The following PR in Mastodon has been updated to make the error easier to identify:
mastodon/mastodon#32792 (comment)
mastodon/mastodon#32850

It seems that improving the error message when passing an invalid string as an argument to IPAddr.new would make troubleshooting easier. This improvement will be addressed in the PR for #70.

Agreed, this error message was very very misleading by Mastodon. And it doesn't seems to be an issue with ipaddr.
