What's the net::ERR_HTTP2_PROTOCOL_ERROR about?

Question

I\'m currently working on a website, which triggers a net::ERR_HTTP2_PROTOCOL_ERROR 200 error on Google Chrome. I\'m not sure exactly what can provoke this erro

Answer 1

I had this problem when having a Nginx server that exposing the node-js application to the external world. The Nginx made the file (css, js, ...) compressed with gzip and with Chrome it looked like the same.

The problem solved when we found that the node-js server is also compressed the content with gzip. In someway, this double compressing leading to this problem. Canceling node-js compression solved the issue.
