Check licence is green, server was rebooted.

Resolving from where?

What DNS servers are you using on the machine?

Are you using split DNS on DHCP?

We are experiencing a DNS resolution issue affecting our 3CX FQDN it.3cx.ru. The main domain 3cx.ru also appears to be unavailable.


Both domains are failing to work, and we suspect this may be a broader DNS issue affecting the 3cx.ru domain rather than a problem with our individual PBX installation.


Could you please investigate the following?

1. Check the DNS records and resolution of it.3cx.ru and 3cx.ru.
2. Confirm whether there is a known DNS or domain infrastructure issue affecting the 3cx.ru domain.
3. Advise us on any required actions or temporary workarounds to restore access to our 3CX system.

Please treat this as a priority, as the issue may affect the availability of our telephony services.


We would appreciate your confirmation of the root cause and an estimated time for resolution.

Please change Cloudflare to any local server operating in the .ru zone (for example, beget.com) and I think everything will work quickly.
Please resolve this issue urgently, or send instructions to those who have an FQDN in the .ru zone (for example, it.3cx.ru) on how to quickly change their FQDN without consequences.
