I've tested my website with mxtoolbox.com and got this message:
Result: The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
I've googled around but I've only found Microsoft related answers that have nothing to do with my webserver. My server is Linux based Centos 6.6 with Nginx 1.8.0 webserver.
Here is the test: http://mxtoolbox.com/domain/poxi.net/?source=findmonitors
What have I tried?
- I've tried upgrading Nginx from 1.7.12 to 1.8.0 and it didn't help.
- I've tried changing Nginx config by commenting almost everything, but it didn't help.
Does anyone have any idea what this error means and how to fix it?
Thanks!
