Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: https://konsolenumbau.expert
I ran this command: none
It produced this output: none
My web server is (include version): nginx 1.11.10
The operating system my web server runs on is (include version): CentOS Linux 7.4.1708 (Core)
My hosting provider, if applicable, is: Alfahosting
I can login to a root shell on my machine (yes or no, or I don’t know): Yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): Plesk Onyx // Version 17.5.3 Update #43
First of all i like to thank everybody involved here for building such a great Community and I´m looking forward to get my Problem solved here.
So, im running the Server with the upper Specs and everything was working fine. Till a week or so.
Problem is, everytime i want to log in my Plesk Panel Chrome and also FF warns me now that my SSL Certificate isn´t secure anymore. This wasn´t the case a week ago and it popped up suddenly like this.
Then when i try to connect to my other Domain “konsolenumbau-luebeck.de” via Outlook, wich is just used to receive Emails now, Outlooks also warns me, that the Cert used for securing EMail isn´t valid anymore.
Error Message is: (sorry i have to translate it via Google) “the goal-principal name is wrong”
As far as i understnad these things thats because the Domain from wich the Certificate was “ordered” is Konsolenumbau.Expert. But why did this work all the weeks before. I run a few other Domains for my Wife. All these Domains are proper Secured when you open them in any Browser but when she wants to fetch her Mails via Outlook the same Error Message pops up. Like on my Mail accounts that wasn´t the case before.
So to bring it on point. When login in to my WebPanel i get that “not secured” Warning and when fetching Emails on other Domains than “Konsolenumbau.Expert” i get an Warning that the Principal-Name is wrong.
What can i do against this Problems?
Thanks a lot I´m looking forward to your suggestions.
Have a great Day you all.
