[> Sun Jul 19 21:30:08.419111 2020] [ssl:warn] [pid 1631] AH01909: 176.9.39.57:443:0 server certificate does NOT include an ID which matches the server name
It is complaining that mpm_prefork causing the issue. This issue is not related to “Hestia Nginx” package or Control panel it self. Requesting an SSL certificate for the control pannel wil not resolve the issue…
i have disabled csf and still the same, if was csf i would not be able to access server at all, but i can view sites running on server it and ssh to iti get internal error 500 when trying to view hestacp.
