Before we proceed, firstly we should explain the role and meaning of the terms used. Not all are technically experienced or have the knowledge. This is why we want to explain for the novice to understand. Please those with the knowledge are humbly asked to bear with us, in quite a while we will proceed.

With running Node JS on an Nginx server, it`s very likable that files such as CSS, JS, etc are being dually compressed. Your file compression might begin its course on the Node Js server then following the action it might happen on your Nginx server because it also does Gzip conversions as a function. Because of this, it is possible to get err_http2_protocol_error.

Clarification: Turn the Gzip compression on the Nginx configuration off. Make sure that Gzip compression-only happens once on your server`s side or better not at all. The problem can also be your header size. Increase value of http2_max_field_size and http2_max_header_size to see if situation is resolved.
