Unable to save options with Reverse Proxy

[Rouzax]

I've always had this issue.
currently running: 5a598fe
Windows 2012R2 + IIS 8.5
Python Version: 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:24:40) [MSC v.1500 64 bit (AMD64)]
SSL Version: OpenSSL 1.0.2h 3 May 2016

When I open Headphones through an IIS reverse proxy everything works except saving the options.

I have enabled the proxy setting in the config

http_proxy = 1

If I open headphones on the internal IP and port I'm able to save the settings. There are no entries in the debug log.
When I look in my IIS rewrite log I see the a 404 error.

I am also seeing this issue with reverse proxy and synology. I do not have http_proxy = 1 set. I can use heaphones as normal however I do see the "error" message. Logs/actions reflect as if there were no errors. Example. If I set an album to wanted I receive the "error" message above but the album is snatched and processed as expected and log shows no error. Every action results in an "error" message.

This issue is happening on Windows with proxy enabled or not.

I'm another one with this issue - I've just installed Headphones today, when running it under the Localhost:8181/headphones (I've set it from this and this works without issue)

When I set up the reverse proxy via IIS (The same way I've set it up for all my other tools, which works without issue) I get the above error.

(I've attached an image from my IIS to show how it is configured.)

I've set up for the "http_proxy" to be set to 1 (And saved and restarted Headphones after)

During all this time I can confirm that the connection via the localhost address works fine, it is just when under the reverse proxy.

Please see below the log I'm getting from IIS (Headphones isn't logging any errors, removed my address from the log):

I've recently migrated to Server 2016 and I can now save.
There is however one draw back, it now loads all pages really slow.
This seems to be because of script.js and jquery.dataTables.min.js
