[Bug] - UI freezes and DefaultAntiforgery error

**Bug**
UI freezes and DefaultAntiforgery error

**Bug description**
Covenant UI freezes after sometime post launching. Please see the attached screenshot. We need to refresh the page in order to get rid of the error. However, post refresh the error still appears.

What I have noticed is that, there is web socket in the browser which sends heartbeats and seems like the heartbeat fails after 3 attempts. Please see the attached screenshot.

I can see the below exception in the logs.

```
Found default JwtKey, replacing with auto-generated key...

Note: I have deleted the image and recreated a fresh docker image on the problematic instance but still the issue exists. I provisioned a fresh instance and did a new installation from scratch and unable to replicate the issue. In fact I tried to reproduce this behaviour by doing fresh installation on newly provisioned vms many times and unable to replicate this behaviour anymore.
