Relay crashes when using CreateAllocationAsync() without specifying region

Hi,

Our game crashes on some devices when using await RelayService.Instance.CreateAllocationAsync(maxConnections) without explicitly specifying the region. When we pass in the first region found it works just fine.

var regions = await RelayService.Instance.ListRegionsAsync();
var allocation = await RelayService.Instance.CreateAllocationAsync(maxConnections, regions[0].Id);

Tested Device: Motorola Moto G(6) from 2018
Unity 2021.3.21f1
Relay 1.0.5

Any update on this? Is there at least any way to manually pick the best server location?

Hey C-Gabriel, we are aware of a bug in the QoS package that can cause a crash on some devices and are working on a fix.

ListRegionsAsync can be used to manually pick the server location as a workaround, see the description field: Class Region | Relay | 1.0.1-pre.6

Hi, good to hear you’re aware of it. Thanks for the update and info :slight_smile:

Hey C-Gabriel, please update the QoS package to 1.2.1 in the project’s manifest.json, this should fix the issue.

Thanks unity-ptrottier, it works well now. for anyone wondering, the package is com.unity.services.qos - we had to add it manually as it wasn’t in our manifest.json
