• What version of Nginx Proxy Manager is reported on the login page?

v2.0.14

To Reproduce Steps to reproduce the behavior:

1. Add 2-3 host configuration with letsencrypt ssl
2. enable http2 for any of the configuration
3. disable the http2 configuration of that host
4. See error - Still http2 is generated for that configuration

Expected behavior not adding http2 to the configuration when database http2_enabled value is 0

@miguelwill http2 is a server-wide port-based configuration. So i think it will be better to take it out from single hosts to some global setting

I’d like some more information on how to disable HTTP2 globally as well.

I’m currently encounter some problems with NGINX/HTTP2 and the easiest solution is to globally disable it but I’m not entirely certain how to do this with NPM.
