Here's the problem
Probably you tried enabling the old spdy protocol on a web server which does not support spdy. Disable spdy option.
That's what's bug.
These are commented out nginx rules, they have no influence on the config of a nginx server at all and therefore they can not produce any errors.
You might want to read here or search for your error ERR_SPDY_PROTOCOL_ERROR in google if you get in your chrome browser:
Till, it's not a settings that belongs in Nginx it's the elements that find it in the previous message.
You believe me or not.
Good to You
Read the links that I posted, they explain that you can not set certain headers in nginx in HTTP/2 mode.
What you posted in #3 are commented out nginx settings to set headers when a page get's delivered.
