[Freeswitch-users] 503 dns resolution failed

[Cédric Clavier]

Hello everyone,

I recently migrate to Kubernetes and to the last release of freeswitch (1.10.7). Freeswitch is running in a docker container based on Debian bullseye.
I’m having troubles with registering my Sip gateway.
Most of the time everything is ok but sometimes, when register is in progress I have logs indicating that there is a dns problem

2021-12-09 13:13:25.635592 73.97% [ERR] sofia_reg.c:2677 studio Failed Registration with status DNS Error [503]. failure #75
2021-12-09 13:13:26.635697 73.93% [WARNING] sofia_reg.c:516 studio Failed Registration [503], setting retry to 5 seconds.

When I scan dns call with tcpdump it seems stuck using dns request for srv and naptr server (none of them exists in my gateway) and does not require the A 

I tried to remove this from my external profile 

<param name="disable-srv" value="true" />
<param name="disable-naptr" value="true" />

But it doesn’t change anything.

Does anybody already have the same trouble or understand what append. 

Thank in advance 

Cédric Clavier
