If you’re on a piefed instance, or are administrating one, make sure your instance is able to receive Fediverse Auth messages

Piefed defaulty rejects DMs from new actors, but this can be fixed in the admin interface by marking auth.fediverse.events as a trusted instance

Edit: trusted actor -> trusted instance

You can also test if your instance works by clicking on the emojis on the Canvas page ✨

I see it failing in the activity log now. It tried sending a chatmessage and a note with the error message: Precheck failed: No digest header present

I can provide the raw json if needed.

Can you send it to hello@sc07.com?

I've sent you a Matrix DM, hope that's okay too.

I've updated YunoHost from 13.0.4 to 13.0.5 (PieFed was already on the latest version) and now it worked. I received two messages from the bot.
