Moved our FreePBX to Vultr in March when employees began working remotely due to covid. It’s worked well until last week when–depending on which WAN connection you were on–some phones randomly disconnected & the GUI wouldn’t load. It effected one WAN, then 2, then back to 1.
To keep this brief, I found that disabling/re-enabling the firewall module or doing
fwconsole firewall disable immediately restored connections. I turned the FW back on & things would be fine for a while (hours) then break again. So I disabled the FW but I’m still getting disconnects. (In fact, the GUI stops responding after several minutes now.) Doing
fwconsole firewall disable still immediately restores connections even though the FW is already off.
I don’t see anything unusual in the logs.
Any thoughts on this would be greatly appreciated.
(Running FreePBX 18.104.22.168/Asterisk 13.32.0 with no updates applied in the past month. Been using Vultr’s firewall the entire time. Disabling Vultr’s FW has no effect on this issue.)
