PJSIP trunk lost connectivity

Hi all!

I am currently doing some testing with a PJSIP trunk on FreePBX 13/Asterisk 13. The connection is against a SIP provider. I have also configured the server of this provider in another Asterisk where I keep a trunk using chan_sip and in this case I do not lose connectivity. I'm not sure why it happens with PJSIP.

The messages I see on the Asterisk CLI are the following:

Any clues where about might be the problem? The server seems to be resolving correctly by making a test using dig

Thanks in advance.

Kind regards,
Daniel
