[jdk]

Reported to me this morning - this was working on the 11 Mar - no changes that I am aware of. GUI not available.

Config test is okay

[root@cr-netmon ~]# apachectl configtest
Syntax OK

httpd error.log file has the following

[root@cr-netmon httpd]# cat error_log

I have restarted the VM, however same issue exists.

Any assistance would be great.

I got this resolved by recreating the self signed certificate on the server. Once I did this, Apache restarted okay.

Hi JDK,

Glad you were able to resolve the issue and thank you for the explanation.

We'll lock out the thread.

Thanks and Best Regards,
Keith
