OpenVidu 2.28.0 CE Failing to keep a single connection We have been using OV CE for a long time now and it works great. We upgraded from 2.27.0 to 2.28.0 and now all connections are failing after a few seconds. We are an online testing company. We have single subscriber sessions to record video of people taking exams online. Please help. We are down and will have to revert.

UPDATE: This was an AWS Deployment. I’ve been able to confirm that this problem only happens if you update OS using these commands: sudo apt update sudo apt upgrade If you just deploy without updating all works correctly. Please consider troubleshooting this for the next release. ---

The AMI is updated each release, why did you need to upgrade the OS?
