Mine I think is a bug as I don't have Nginx even on! I'm new still so I can submit it

Hi Laughing Steam,

I don't have Nginx even on!

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).

Hello, you are trying to decide it is bug or not. Nice but there is a problem also I and users have a problem you have to find solution instead of discuss about it

 

[Bitpalast]

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.

Oh sorry, I saw "Plesk Guru" tag then I think you are developer team. I want to thank you because you are discussing trying to find solution.

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 !!

what about the work round? will it be overridden

 

[Bitpalast]

You have already asked the same question in the other thread. The answer is the same, too: It does not matter. Just leave things in place as they are on your system. If the update thinks it must update the file, it will overwrite it, but then it will still work. If the update does not overwrite it, it will continue to work. Either way, it will work.
