I’m using Unity 2021.3 LTS, with 4.0.0-pre.4 (The last version to support 2021.3). I’m finding that the Face Capture app works well initially, but after a couple of minutes, it shows a message in the app “Disconnected from server”. It then takes maybe 30-60 seconds to reestablish a connect, as I close/reopen the app, stop and restart the App Server in Unity, and generally do a bunch of stuff that possibly has no impact on the problem. It seems I can’t use the app for more than a couple of minutes before it disconnects like this.
I do see some inconsistent error messages appearing in the console around the time the disconnect happens, but I’m not sure it’s related. I’ll include those messages here. But mostly I wanted to know if there was some other logging I could enable to better explain the cause of the disconnection?
My iPhone is on the same local Wifi network as my PC, and I’ve made sure the firewall is open, and that the app has access to the local network. Is there anything else I can look at to make the connection more stable?
