### Please select what you are reporting on:

Unreal Editor for Fortnite

### What Type of Bug are you experiencing?

Stability

### Summary

Every time I launch a session, I can see in the log timeouts to private IP addresses, and retries and timeouts to urls like [https://content-service.bfda.live.use1a.on.epicgames.com/api/content/](https://content-service.bfda.live.use1a.on.epicgames.com/api/content/). It takes 6 retries before the session successfully launches, and this happens every time.

### Steps to Reproduce

1. Open a UEFN Project
2. Launch a session
3. Look a the Output Log, multiple warnings and retries will appear

### Expected Result

It should connect immediately to a session rather than timing out 4 to 6 times before succeeding.

### Observed Result

The session eventually launches, but we observe these errors in the Output Log window:
