Please try to comment and post things now, and see if they federate again.

Hopefully you see your activity instantly federated. I have tried making comments both to instances running Lemmy 0.19.1 and 0.18.5 and they all federate like they should.

Hope you have the same experience! 🥳

I am reading this from lemmy.fan so you're definitely federating now!

Thats great. :)

I know other instances on 0.19.1 had issues with federation so I can share what we did here to try and fix it.

There is a database table in postgres called instance and in our case, it had thousands of instances that were considered dead. Our instance didnt seem to try and talk to them anymore since the "updated" column would never update.

So we ran a simple database query to set the updated column to now() for all instances that we knew about:

update instance set updated = now()

This caused Lemmy to go out and try to talk to all of the instances again, and reconsider if they were dead or not.

According to this site we are now federated with 3000+ instances again:

I hope we stay federated this time. Will keep an eye on it. :)
