Recent EOS Backend Changes ?

Hello!

Has there been recent changes on the backend side of Epic Online Services? We have several network issues that appeared in the last few days. We first suspected a regression introduced in our code, but these issues affect older versions like our Early Access that had been tested for network issues before being shipped to the public.

We tracked the issues to a Session Invite failing with code “session_failed”, and upon inspecting Sessions in the backend, it seems like players are no longer registered and Session Invited remain Pending and are never resolved.

We made no change in our code regarding Session management, and as I said, we are able to reproduce the issue on earlier shipped versions that had been tested and validated.

The apparition of the bug seems to match the day I received a mail from Epic Online Services warning about changes in the ECom service, that I ignored because I do not use this service. But I found no mention of other changes in it.

Please let me know if there was a change and how to adapt, we are one week away from launch day and we could really use some help!!

We also encountered an issue related to errors.com.redpoint.eos.sessions.invite_failed. This issue appeared on April 15th and also affected our builds retroactively. Fortunately, we were able to solve this by unchecking the “Manage Players” action in the “Matchmaking Service” from our client policy (in the EOS backend). We don’t really understand why, but this worked for us.
