Video Bridges No Longer Connecting to Jitsi

I’ve created several video bridge instances and they are no longer able to connect to the jitsi server.

I’m seeing this in /var/logs/jitsi/jvb.log:

The jitsi server is working with its videobridge service running on the same box.

Were they connecting fine before? You were able to host 3-party calls on each bridge successfully?

Yes, they were working before. I tested by turning off the various video bridges and turning them on one at a time. I did notice this today in my prosody logs on my jitsi server. Perhaps it is related:
