This is a scenario I didn't anticipate. The only reason this.http_server could be null is (1) the ServerStartedEvent was not sent or failed, or (2) the ServerStoppedEvent was sent twice.

Are there any other errors occurring during start-up? Does the server start up properly without the Prometheus-Exporter mod?

There is not any errors in startup, just this. Anyway, now I could not check the server logs because I completely upgraded it, sorry. Just remember that I restarted the server and now it works. Probably startup order error.
