Me and a few of my colleagues got "net::ERR_SPDY_PROTOCOL_ERROR" error on our site today.
We are using ngix ver. 1.8.0. Unfortunately, the error both appeared and disappeared and it can not be reproduced. Google didn't help us. What is this error and how can it be fixed? Thank you!

Colleagues accidentally don't have Avast ? There was such a problem. Disabling HTTPS scanning in the web screen settings was solved.

I had a similar error on a site that also worked on nginx. Moreover, a lot of these errors poured into the console and it was for images. As a result, the problem turned out to be in the nginx "send timeout 2" setting. Those. too little timeout was set for sending the resource and nginx failed to load the images in 2 seconds and broke the connection.
PS The problem, of course, is not so much in this parameter, but in, at that time, not optimized images.
