Resolved Apache down

UHolthausen

Regular Pleskian
Hello

I checked the server yesterday morning and everything was fine.
Come home at noon, several mails that apache cannot be started.
plesk repair web didnt help.

Nothing was changed, only for test purposes the php version was changed to 8 and then undone.

apache log reports mod_ssl problem: AH02311: Fatal error initialising mod_ssl, exiting.

AH01898: Unable to configure permitted SSL ciphers
[Sun May 16 09:47:21.874045 2021] [ssl:emerg] [pid 14202] SSL Library Error: error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no cipher match

plesk:

Every hint for a solution is welcome
 
Is it this?

I have not yet seen this issue myself, but I suspect that it can be solved by removing the checkmark from the Mozilla TLS/SSL ciphers on the SSLIt-configuration of domains.
 
Hello Peter

You made my day, its solved.
My os ist debian 10.9

I changed the setting from modern to balanced and it works again.

Addition:

The server was running with the setting "modern" since october 2020, what caused this problem from one day to the next?
