Some websites can't use let's encrypt SSL certificates

I have an issue with let's encrypt.
I created ssl certificate on domain, server.domain1.com without problem and properly signed.
After that I create domain2.com website with alias and created SSL cert. on that alias. This also worked.
But when I created SSL certificate for domain3.com with Let's encrypt enabled (like in previous ones) and look in settings of that website SSL and Let's encrypt ssl are both disabled (still enabled in domain1.com and domain2.com site settings) and when I try to access domain3.com Chrome tells me that domain3.com uses domain2.com certificate.

I running Debian 9 with Apache2 and ISPConfig Version: 3.1.14p2

Thanks for any suggestions on my problem.

 

Certificate creation failed for domain3 for some reason.
