Vesta Control Panel - Forum

Hey, i have major problem with Vesta (I suppose it's related with DNS).
Up to today everything was working like a charm, but right now EVERY domain cant reach DNS servers, so my websites, and emails are down, restarting services, or whole server does nothing. I dont know where to start search problem origin.
I'm using up to date Vestacp on CentOS 7.3.1611

You need to post more information,

DNS LOG?

try to restart dns, look at the error.
