<![CDATA[NodeBB 4.13: activitypub/fetchPublicKey Rate limit exceeded errors.]]>@kichae@community.nodebb.org can you try again with the latest develop commits?

A couple things:

  • You can now set the rate limit value to 0 to disable it completely
  • The logic was a mix of both a db-backed mutex lock and a rate limiter, which was overkill. I think what happened was Lemmy (or other popular instances) sent many activities all at once, causing the rate-limiter to trip, even though the value was well under the threshold.

The default is now updated to 256 but if you've overridden it your value stays. I'll keep an eye on Lemmy federation to see if that was the issue...

Error rates have crept back up, so there's more debugging to do.

For me, lemmy.world hasn't started re-sending activities yet, but it will... <img class="not-responsive emoji" src="https://activitypub.space/assets/plugins/nodebb-plugin-emoji/emoji/android/1f440.png?v=9937f999e94" title=":eyes:" />

Once Lemmy decides your server is "down", it won't send anything for awhile. How long that is I don't know offhand.
