Hello, I've a old server with Debian Jessie (the old old stable) with Nginx. Such Nginx version does not support http2 but last version of ispconfig will enable it on configuration files. This leads to errors when Nginx is reconfigured. Where I can disable http2 support? Thank you L.
Preferably in ISPConfig CP but I always thought ISPConfig will detect that before showing the option to allow you to use http2.
Just for reference: You can do that by creating custom nginx templates for the website vhost, ispconfig vhost that don't use http2.
I think this previously was related to spdy settings which can be turned off, but since the user is upgrading, and hopefully installing nginx with http2, this shouldn't be a problem anymore.
