Bridge Behaviour pbx V16 SP4

[AWS2P]

Hi,
I have a V16 SP4 on premise PBX (windows 10) with slave bridge set, on master side I have a cloud OVH V16 SP4 PBX (debian 9).

Bridge is going down randomly almost 2 or 3 times a day and take about 2 minutes to get back up alone, I got this in activity log and events :




What can be understood from this? if it was a DNS failure i should have same problem with trunks too but the only problem is with bridge.

The "DNS error" is a bit misleading, it says services are not available/IP isn't reachable..

Maybe you could try to catch the moment it arrives in a packet tracer and have a consistent look at the network..

Hi Mathieu
As I said, this is happening randomly so i can't capture hours of traffic, in same time only bridge is going down not the trunk, so if it was network or DNS, I guess it should be for all traffic concerned not only bridge.
