We just released a new patch which fixes an important federation problem. Due to a mistake in the code, activities were only sent out once, even if delivery failed (e.g. because the target instance is down, or a temporary connection issue). Instance admins should definitely upgrade.

This problem is fixed, so that failed deliveries are retried up to 9 times, with exponentionally increasing intervals. The only limitation now is that it will not keep retrying after Lemmy is restarted, but that case should be less common.

    Damn, it looks like there are additional problems with federation. We will release 0.16 in the next days which will include additional logging, and allow me to debug this.

    To rule out the firewall, the main thing you need to ensure is that POST requests to /inbox go through.

      Yeah, according to logs the POST requests are going through fine.
