Are you using the same user name? I had a similar issue with my local instance, ended up just having to make a new user name, since the previous one was already known about, even though all of the other instance says was different. So it wouldn’t federated my posts and comments. Admin tried a bunch of stuff to no avail.

Oregon is definitely an example for other states to follow in this regard.

As I understand it, there is a way to format links that will open the community on your current instance. I’ve seen people say that, anyway, but don’t know what that link format is.
