Had to reinstall Lemmy - did I break federation?

I’m wondering if this post will even go through**. Long story short, I had to rebuild my Lemmy instance without importing the old data. I manually recreated my account (Knova@links.dartboard.social) and was able to subscribe to communities (although everything says “subscription pending”*). But it doesn’t seem like my posts federate properly.

*additionally, a third party Lemmy app I use does not recognize my subscriptions when they are in this pending state, further driving me to conclude it’s broken.

I made a new account on my instance to see if things were broken, and under a new name things seem to be working. Is my original username doomed to purgatory?

**test - posted this originally from the KNova account but doesnt look like it hit the lemmy.ml server. See here - https://links.dartboard.social/post/7176 - trying to repost from my other account now.
