Steps to Reproduce

1. installed self-hosted successfully in my owner server with all docker up healthy.

2. installed sentry unity sdk with upm.

3. started monitor my unity project with sentry unity sdk using follow test.

SentryUnity.Init(o =>
{
    o.Dsn = "http://b47cae695xxxxd7a46@host:9000/11";
    o.Debug = true;
    o.TracesSampleRate  = 1.0;
});

}
catch (Exception ex)
{
    SentrySdk.CaptureException(ex);
}

Expected Result

And my self-hosted got nothing

[aminvakil]

AFAICS this is related to sentry unity sdk, do you have a reason to believe it's related to self-hosted? Does it work with Sentry SaaS ?

[ismeyueyue]

@aminvakil thanks for your replay.

well, it worked on the sentry.io using the same code.

I think the self-hosted is set up successfully which I can open the web link http://host:9000/, is there any other way to verify it, and help me to figure out this problem

[aminvakil]

If you have a reverse proxy in front of your sentry (9000 port), try bypassing it and hit sentry on 9000 port directly.

Also try docker compose logs -f and send your request, then see if you can get a clue from logs.

I believe this is really https://github.com/getsentry/sentry-dotnet/issues/1817, since the Unity SDK depends on the dotnet SDK.

@bruno-garcia, does that makes sense? If so, is the fix here a new sentry-unity release? Looks like the dependency was bumped yesterday: https://github.com/getsentry/sentry-unity/pull/911

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
