The Plesk Control Panel IS a combination of NGINX and LiteSpeed ( compairable with apache ) and is named "sw-cp-server". It has got absolutely nothing to do with your very own nginx version and apache version installed on your server to serve your domain(s).I don't have Nginx even on!
We're all users, not Plesk team members. Plesk team members, Plesk support and Plesk developers are separate. This forum is a user forum. You and us can file a bug report equally well. We've been reflecting and discussing whether it is a bug, because before filing a report with Plesk, it is simply nice behavior to only cause work if it is really a bug.
I had same thing after upgrading to 17.5. However similar issue was in Plesk 11.
So - I have added to:
/etc/sw-cp-server/conf.d/plesk.conf
below line:
error_page 497 https://$host:$server_port$request_uri;
restarted sw-cp-server and issue has been fixed.
I have followed this article.
server_names_hash_bucket_size 64;
server {
listen 8443 ssl;
listen 8880;
listen 127.0.0.1:8880 default_server;
include conf.d/*ipv6_ports.inc;
ssl_certificate /usr/local/psa/admin/conf/httpsd.pem;
ssl_certificate_key /usr/local/psa/admin/conf/httpsd.pem;
include conf.d/*plesk.inc;
include conf.d/*wpb.inc;
error_page 497 https://$host:$server_port$request_uri;
}
work !!
/etc/sw-cp-server/conf.d/plesk.conf
.
