Troubleto enable HTTP2 whit Virtualmin

Hey there,

Can you share the exact steps/commands that you’ve executed in order to enable http2 so we can check them together?

Normally you will enable HTTP/2 using the a2enmod http2 command and then a few more steps will be required.

1. Ensure that you are using the Apache MPM event worker. If you aren’t sure, you can switch to MPM event by running these commands: a2dismod mpm_prefork a2enmod mpm_event
2. Edit your Apache VirtualHost configuration for your website and add the line Protocols h2 http/1.1 inside the <VirtualHost> section.
3. Restart your Apache service with the command service apache2 restart.

If you’ve completed these steps and are still facing issues, it might be related to your SSL/TLS configuration. Make sure you have valid SSL/TLS certificates and the proper configuration for them.

Hope that this helps!
