net::ERR_HTTP2_COMPRESSION_ERROR - WORDPRESS

Okay, I hope this will help many. I have been experiencing this for many weeks. My apology because I am using WordPress.

net::ERR_HTTP2_COMPRESSION_ERROR only occurs on Chrome:Incognito.

I have Cloudflare for my CDN and caching HTML - and W3 Total Cache - for minify js, css and Page Cache, OP-Cache, Object Cache, Browser Cache.

now, after countless of trouble shooting, I detected the issue when disabling the "Browser Cache" after that, I fixed the problem when

I modified the Browser Cache ( go to side panel )

find the ("HTTP Strict Transport Security policy") make sure its checked. under that is directive set the value to - max-age=EXPIRES_SECONDS; includeSubDomain: preload

take note that I am using sub-domain.
