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

This error is currently being fixed: https://chromium-review.googlesource.com/c/chromium/src/+/2001234

But it helped me, changing nginx settings:

• turning on gzip;
• add_header 'Cache-Control' 'no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0';
• expires off;

In my case, Nginx acts as a reverse proxy for Node.js application.
