Hi Christian_Heutger,

there are several solutions/suggestions here at the Plesk - Forum and over the Odin/Parallels - Knwoledge-Base. If you experience any issues/problems, please describe your issue/problem and let us know your operating system, your Plesk version ( incl. MUs ) and probably add log - files and/or configuration files, so we can help you with investigations and suggestions.

Ehm, I paid for an "optimized computing" solution like Plesk to have it done by plesk and no listing of configuration files, I can adjust by myself?! However I'm afraid that won't set dhparams for all existing and future sites?

Hi Christian_Heutger,

You would need to copy the templates for Nginx with SSL Directives from..

/usr/local/psa/admin/conf/templates/default/

to

/usr/local/psa/admin/conf/templates/custom/

And then edit to add the dh_param directive.

You must also keep the directory structure, so

/usr/local/psa/admin/conf/templates/default/domain/nginxDomainVirtualHost.php

Must be copied to..

/usr/local/psa/admin/conf/templates/custom/domain/nginxDomainVirtualHost.php

Then you'll need to rebuild your domains with...

/usr/local/psa/admin/bin/httpdmng --reconfigure-all

I hope that helps
Kind regards

Lloyd

well thats a solution for the vhosts, but what about the Plesk Panel itself?

Hi Brujo,

the search over the forum ( keyword "dhparam" in the forum "Plesk 12.x for Linux" ) would have pointed to this post as well:
