Cody Deluisio | Unifi WebSocket Connection Error Unifi Controller 5.12.66

 

Today I ran into an error after upgrading my Unifi controller that I really wasn’t able to find much online about. What I could find online was simply saying to update my controller or turn off WebSocket connections.

This turned out to be something very simple. But here is how this all started; my controller had been consuming RAM like no other. In the span of a month, we went from 1 GB provisioned with no issue up to 16 GB 100% usage. After turning Wifi AI on RAM usage never decreased. So I decided to spin up another controller from scratch and start fresh.

I restored my old backup settings and upon loading the controller was greeted with the above messages. I could make any changes that I wanted but after 2 minutes I had to log in again as I’d get a fatal error.

Looking the issue up online I saw it suggested to just turn off WebSocket connections. I was able to turn the setting off but it appeared to have no effect. Even with WebSockets off, I was still getting WebSocket connection errors. A few reboots and nothing.

This 30-minute job was quickly turning into an all-day ordeal. So I figured now is the time to dig into the logs. I log into GCP and go to the logging section; GCP is really good at locking me out when I need it the most though and today was that day.

With that there was no packet captures to be had; that’s when I realized the issue, the SSL cert wasn’t valid for where the controller was currently parked. A new SSL cert and the issue went right away.

Today was a very short write-up but I’m hoping it helps anybody else that runs into this – have a good night.

Cody Deluisio - What Is A Network Engineer?

F rom the outside, the whole information technology profession can seem mysterious. Mentioning IT summons various images ranging from artificially-lit cubicle farms to young professionals roller skating through well-decorated lounge spaces that feel more like a coffee shop than a workplace. Both are valid, and examples of both can be found. However, there really is quite a bit of difference. For example, network engineers are the people who keep the internet running.
