I’m attempting to run some tests on my deployment and I know that it’s possible to disable HTTP/2 when using Nginx. But, for a Phoenix app running on Fly.io is there a way to disable HTTP/2?
I’ve tried changing the following settings in my toml.
[http_service]
...
[http_service.tls_options]
alpn = ["http/1.1"]
[http_service.http_options]
h2_backend = false
[services]
[services.ports]
handlers = ["tls", "http"]
port = 443
[services.ports.tls_options]
alpn = ["http/1.1"]
versions = ["TLSv1.2", "TLSv1.3"]
[services.ports.http_options]
h2_backend = false
