HTTP2 stream 1 was not closed cleanly

DimasFrolov · Sep 7, 2018

Hello everyone,

I've installed in my WHM panel mod_http2, but I still didn't get HTTP2 headers when I request it in curl. And I get this error:
Code:
curl -I https://example.com
curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1)
Does anyone know how to fix this problem?
Thanks.

Nobody see this error before?
My server response only via HTTP/1.1

Hello @DimasFrolov

This error is usually associated with content that is not able to be served over HTTP/2 - typically remote content. You can test individual resources to see how they load with something like the following as well as your site itself:
Code:
curl -vvv https://yourdomain.tld/path/to/resource 2>&1 | grep HTTP
