Hello, the peak radio association is operating about 30 conecting to our Hub (47178) running in the cloud on Vultr with current ASL3. over the pas 3-4 weeks, we have random nodes that will drop from the hub and when I log into those nodes the auto reconnect is attempting to reconnect and it shows “hung up” and auto congestion. Restarting the node does not fix it. If I take the node off line until Allstar link shows that its no longer registered, then restart, it connects again and will last 30mins - 12 hrs and then fail again. I changed our hub to IAX2 registration and disabled HTTP - no luck. still the same. any ideas on how to go about figuring this out?
