Solved stun-eu.3cx.com failed !

[Cédric B]

Hello,
I have a problem this morning, it is impossible for our installation to communicate with the 3CX server.
In addition, the administration page is no longer accessible with the FQDN.

resolving 'stun-eu.3cx.com'... failed (How to resolve?)
resolving 'stun2.3cx.com'... failed (How to resolve?)
resolving 'stun3.3cx.com'... failed (How to resolve?)
resolving 'sip-alg-detector.3cx.com'... failed (How to resolve?)

Do you have an idea ?
Is there a page where we find all the statuses of 3CX Servers ?

Thank you in advance for your help.

Hi there,

I can confirm that there isn't any issue with our STUN servers nor have we received any report.

Thank you for taking the time to look on your side.
After your answer we checked our firewall was the cause of the blockage despite no modification in it.

No worries, glad you worked it out. I'll go ahead and mark this topic as Solved.
