Cannot reproduce?
Try this

/// add to CustomMission class
override void OnClientReadyEvent(PlayerIdentity identity, PlayerBase player) {
        super.OnClientReadyEvent(identity, player);
        RestApi restApi = CreateRestApi();
        restApi.EnableDebug(false);
        RestContext restContext = restApi.GetRestContext("https://api.cftools.cloud/gamelabs/dz");
        restContext.SetHeader("application/json");
        restContext.POST_now("/v1/trace", "test");
    }

I guess the important difference might be that this request is done after the Hive is initialized

Actually no its not that.
On my server it works in init.c
in main() before hive init
in main() after hive init
in OnClientReadyEvent

cannot reproduce any crashing

Actually this crash seems to just be a generic memory allocation crash. Not related to web requests itself.

It pretty much sounds like you ref'd the RestCallback instance somewhere... you should not use refs on them under any circumstance

That's it, refing it all the time.
