Upgrade from YT 5 to 6.5 HTTP POST not supported

Same here on Windows 2012 R2

Hi Daniel,

my colleague said that he got it running with these setting:
https://confluence.jetbrains.com/display/YTD65/Linux.+JAR+in+Nginx+Web+Server
I did not get around to confirm it yet, but maybe it helps you.

I can verify that the instructions under https://confluence.jetbrains.com/display/YTD65/Linux.+JAR+in+Nginx+Web+Server solved the problem.
I think most critical for our system was the following line:
proxy_set_header X-Forwarded-Proto https;

Daniel Fisher, did you ever solve it on windows 2012? I have the exact same problem... All the solutions posted are for linux.

I can confirm this problem, and on apache2 it can be fixed with this instruction:

RequestHeader set X-Forwarded-Proto "https"

You need to have mod_headers enabled.

I have what's below, but I keep getting the error message.

Could you please open a support ticket on this matter: https://youtrack-support.jetbrains.com/hc/en-us/requests/new ? It would be more convenient for detailed investigation.

I can also confirm this error can be firxed by adding the header "X-Forwarded-Proto" with value "https", whatever the proxy server is (Apache, NGinx, Express, Koa, ...). This happend because I was using a reverse proxy to forward requests from the internet (in HTTPS) to an instance of YouTrack Standalone using HTTP.

This header needs to be set for this HTTPS -> HTTP -> HTTPS bridge to work.

Lius, thank you for sharing the solution!
