You can fix Logjam for the Plesk Panel by simply adding the standard Nginx dhparam directive to the plesk.conf file.
Very similar to previous posts on adding OCSP and HSTS to Plesk.
First you will need to create your dhparam, you can follow my guide Creating DH Parameters, and then locate the file and edit with your favourite editor…

/etc/sw-cp-server/conf.d/plesk.conf |
And add the Nginx ssl_dhparam directive above the certificate entries like so…
|
1 2 3 |
ssl_dhparam /etc/ssl/dh/RSA2048.pem; ssl_certificate /opt/psa/admin/conf/httpsd.pem; ssl_certificate_key /opt/psa/admin/conf/httpsd.pem; |
Save the file and restart the Plesk server…

service sw-cp-server restart |
And you are good to go.
I hope that helps someone.
