Lemmy should never fetch anything from an HTTP URL in production mode, this is checked [here](https://github.com/LemmyNet/activitypub-federation-rust/blob/main/src/config.rs#L144). And [here](https://github.com/LemmyNet/activitypub-federation-rust/blob/0.5.1-beta.1/src/fetch/mod.rs) is the relevant fetch code used by Lemmy 0.19.3 which correctly calls...

Hmm it logs a lot of errors for "Failed to generate thumbnail", but those should be ignored and not prevent it from fetching the community. Anyway you can try if...
