Can't add more than two domains in Vesta CP
I'm running Vesta on Ubuntu 16.04 and met a strange problem - I added two domains already in Vesta and both works fine with HTTP or HTTPS (Let's Encrypt). But when I try to add a third domain it doesn't works (not available via browser) and what is more strange that all other domains also goes down... When I delete this (third) domain, other domains becomes alive again...
Does anyone met the same troubles? Any ideas?
