Hi All

I am running Nginx 1.10.0 on Ubuntu 16.04

Since last week I am getting ERR_SPDY_PROTOCOL_ERROR loading 2 .css files from my site and it only occurs on Chrome.

I tested on Firefox and Safari and do not get these errors.

This morning I upgraded Chrome from 58.0.3029.110 > 59.0.3071.86 but still the errors are occurring.

Could this be an Nginx 1.10.0 issue? Should I upgrade to 1.10.3 ?

Nothing has changed in any of my nginx config files at all.

I am running my Nginx sites with "listen *:443 ssl http2;" and not using SPDY at all so why is Chrome doing this ??

I have monitored my Nginx access and error logs for the sites concerned and all assets including the css files that chrome says are not loading are actually being served with a 200 OK response or sometimes a 304 not modified response.

Any help or pointer to solving this will be greatly appreciated.

There have been some bug fixxes regarding http2 since your version (http://nginx.org/en/CHANGES).

I'am running NGiNX stable (1.12.0, http://nginx.org/en/linux_packages.html#stable) on ubuntu 16.04, http2 enabled wit no problem. I'am not saying it will solve your problem, but because there have been bug fixes regarding the http2 protocol since version 1.10.0 it could help.

Thanks Wilfried I will try moving up to 1.12 been meaning to do it and think it's time now. I did eventually trace my current issue with the two CSS files not loading down to an issue with Nginx fastcgi cacheing. I set a nocache rule for the folder that contains those two CSS files and the SPDY error on Chrome went away but I do believe I need to move up to latest stable release.
