Problems posting a new topic

I’m trying to create a detailed post and I’m getting an error message that says, “Sorry. New users can only have 2 links in a post” (Or something along those lines.) But my post only has one link.

I think the problem is that the error messages I’m including talk about a package called “containerd.io” (it’s mentioned more than once) and it looks like that’s being treated as a link.
