hi @PledgedRanger ,  
A Major Problem is network gateway address being corrupted

```auto

HttpRequestException: https://urc-api.ucs.on.epicgames.com/v1/projects/6455cc10-4532-b6c9-44ff-caaa1b9dc67b/paths/state -
 ***502 - BadGateway***

```

Then when my pc tries just get a “No valid authorization received”. Meaning my network connected correctly

```auto
{
    "ok": false,
    "code": 401,
    "message": "{\"code\":\"Unauthorized\",\"message\":\"No valid authorization received\"}"
}

```

Someone else just had problems with browser cache corrupted causing network problems

 ![Clearbrowsercache](https://d3kjluh73b9h9o.cloudfront.net/original/4X/c/b/2/cb27609421df9dd54a8873be314417e6ba0a45f1.png)

Do you have any Firewall software like Zone Alarm which blocks addresses.  
Do you have VPN which would use different gateway.

Fixing Delmar errors  
On My PC deleting the Delmar directory. UEFN still starts up fine without the Delmar directory

 ![DeleteDelmar](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/7/0/47073773395e9939b10117274c0abdf30a39eb3f.png)

```auto
C:\Program Files\Epic Games\Fortnite\FortniteGame\Plugins\GameFeatures\DelMar

```

Now run “Verify” from the link below to put back the corrected 30.40 Delmar directory

Summary  
The main problem is the network connection.  
Until this is sorted out nothing will really work
