I was pointed here from the issue I created on github:
TL;DR my instance (although it’s pretty generic in what software it is running) seems unable to accept remote-follow requests I perform on other instances. The other instance just fails with a typical “oops” message. The problem disappears when I disable ipv6.
I’d like to understand what may be misconfigured on it, since it seems to be a problem which people encounter a lot, and which they solve by disabling ipv6, but which is in my opinion more of a way to avoid the problem instead of a way to really solve it.
Can someone provide me with any tests/pointers/snippets/reading materials which I may use to check my ipv6 configuration to understand what’s wrong?
Thanks in advance for your help!
