Hi there! Since hours I try to enable the http2-module on my Debain-9-Server, running Apache 2.4.25 and ISPConfig 3.1.15. First of all: The module is successfully loaded, i checked it several times. Unfortunately there are a lot of tutorials in the web, each of them prefer another way to get http2 enabled - in my case: Nothing work :-( My first and simple try - Using the Web-Interface of ISPC: Websites -> mydomain.xy -> SSL -> Activate SPDY/HTTP2 (Apache Restart) Second try - Using Web-Interface again: System -> Severconfig -> Web -> SSL -> SPDY/HTTP2 Third try: Editing the Vhosts for may websites manually: Code: <VirtualHost *:443> Protocols h2 http/1.1 # ... # ... </VirtualHost> Last code I also tried in the global config-files, but nothing worked for me. Is there anybody who can help?
