We have 2 environments were WAF is configured.
In the DEV environment, its working on http2
In the UAT environment, its not working on http2. When the WAF configuration is change, it works on http1.1.
I have provided some detains below (you will see that the clusters are running on different versions etc)
What can i do to have the configuration work on the UAT environment with http2?

From your verbatim, you have 2 Application gateways,
- DEV App Gw - HTTP2 works
- UAT App Gw - HTTP2 does not work
Can you confirm if HTTP2 is enabled in UAT App Gw? By default, HTTP/2 support is disabled.
- See : Enable HTTP2 support
- Can you share a screenshot of HTTP2 being enabled.
NOTE : Communication from AppGw to backend server pools is always HTTP/1.1
If HTTP2 is enabled,
- May I know how you are validating the HTTP2 support?
- Are you using curl --http2 <DomainName> or a third party tool ?
- Please share the results
Thanks,
Kapil
