[Voytda]

Hi!
Our self-hsted phonesystem use FQDN at zone 3cx.ru

From this morning It not resolved anyway.
Check licence is green, server was rebooted.

Site 3cx.ru also not work.

How we can resolve this issue?

Resolving from where?

What DNS servers are you using on the machine?

Are you using split DNS on DHCP?

Not resolving from anythere. dnschecker is in red crosses. Mobile clients cannot connect.
DNS is 8.8.8.8 and 77.88.8.8
yes, we use split DNS, inside our infrastructure are working well
