Hi everyone, some context: Database is in East US (North Virginia), XLarge, with a read replica. Postgres is V15 (moving up to V16 or V17 is not an option right now). My client is built using Flutter, deployed both as a web and mobile app.
I've made no changes to the database or clients in the past few weeks. Reportedly, realtime stopped working at all three or four days ago. I've tried restarting the project, disabling and enabling the publication and individual table's realtime, setting replica to full, checking for ad blockers, etc. There really seems to be a problem with my project's realtime in general (all clients have stopped receiving realtime updates).
Does anyone have any idea what might be going on? Any similar experiences or ideas on how to fix this?
