• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.
  • The ImunifyAV extension is now deprecated and no longer available for installation.
    Existing ImunifyAV installations will continue operating for three months, and after that will automatically be replaced with the new Imunify extension. We recommend that you manually replace any existing ImunifyAV installations with Imunify at your earliest convenience.

Question How to activate http/2 for Plesk panel

HTTP/2 (also known as HTTP/2.0 and HTTP 2.0) is the second major version of the HTTP network protocol used by the World Wide Web. Ratified in May 2015, HTTP/2 was created to address some significant performance problems with HTTP 1.1. The advantages of this protocol can be found here. Currently HTTP/2 is supported by most major web browsers.

HTTP/2 support is available for Plesk customers starting from the version 12.5.30 Update #28 and requires the latest version of nginx.

How to Enable HTTP/2 support for your web site
Make sure you have nginx web server updated to the latest version and running. You can do this on the Tools & Settings -> Server Components and the Tools & Settings -> Services Management pages.

Login to your server via SSH under root and enable HTTP/2 support in Plesk using the following command line utility:
Code:
# plesk bin http2_pref enable
During the last step your nginx web server will be tuned to use the TLS protocol with modern and secure ciphers, the whole web server configuration will be rebuilt, and all your and your customers’ web sites with SSL support will be moved to HTTP/2.

Please check the output of the command for errors or warnings during switching to HTTP/2. If there are any problems, refer to the Troubleshooting section below.

If you wish to return to HTTP 1.x and to disable HTTP/2, please use the following command:
Code:
# plesk bin http2_pref disable


For more information & troubleshooting, look here: HTTP/2 Support in Plesk
 
You can create your hostname, as a domain in plesk, than enable http/2 for this domain.

Than connect to plesk with your.domain.com:8443

If you have any further questions, let me know.
 
And when i activate this by server. I mean there are two different environments at my server. 1 for Plesk and the other ones for my websites.
 
I'm over-excited, I can not think of a global setting for the system outside of Plesk except this:
Code:
plesk bin http2_pref enable
