I've made that attempt but it doesn't change, now I'm looking at the nginx configuration for a moment, but the problem is that it's on all the domains, but until yesterday it was running without problems, that's what I don't understand
the domains on server a are using an ssl certificate from a domain on server B, now I do not understand how this can be.
and includes 3 servers of which 1 is not used only as a mail server so it does not have all the domain names and above all it does not have the ssl certificate which is out when browsing or accessing emails , which is present as said only on 1 server .
I hope I have explained myself
