Short summary
Requests across multiple characters silently stopped getting responses after July 27
What happened?
I’m using Convai Unity SDK v3.3.0 (gRPC) with multiple characters active simultaneously in one scene, each on its own gRPC connection — including Fatima and Layla (Layla is a translator/interpreter relative to Fatima). I talk to them via triggers (e.g. “TriggerTranslation” on Layla), live audio streaming, and text sends (e.g. forwarding Fatima’s translated response to Layla as text). It’s normal for two characters’ sessions to be active at once.
A full scenario with both characters worked repeatedly on July 27. Re-tested July 29 with zero code changes — same build — and it’s failed every time since. Requests (across all three types: triggers, audio, and text) now intermittently get no response at all — the client just hangs waiting on the stream. WriteAsync/CompleteAsync succeed, but MoveNext() in ReceiveResultFromServer() just hangs forever. These requests don’t show on the Convai dashboard either. I’m not sure whether I’m hitting a concurrency issue or not, and if I am, why it was working on July 27 and before that.
I’ve spent two days debugging my own code with no changes found — since this touches my whole architecture, I wanted to check whether something changed server-side before restructuring further.
Could you check: (1) any concurrency-limit changes around July 27–29, (2) backend/infra changes in that window?
