Calibre Reverse Proxy Mac High Seira

Vanguard382 · 01-15-2019, 02:27 PM

Greetings!

Apologizes if this question is on the novice level when it comes to reverse proxy/apache configuration.
I have a Calibre server that runs on my Mac Server running OS High Seira.
In the past I was able to access Calibre through an apache reverse proxy I had configured.

My apache .conf for calibre is:

# from http://httpd.apache.org/docs/2.2/mod...html#proxypass
RewriteEngine On

RewriteCond %{HTTPS} =off
RewriteRule . - [E=protocol:http,E=port:80]
RewriteCond %{HTTPS} =on
RewriteRule . - [E=protocol:https,E=port:443]

ProxyPass /calibre http://localhost:51269/calibre
ProxyPassReverse /calibre http://localhost:51269/calibre

In the past I had no problem going from my external facing hostname to /calibre and access all pages.
Now attempting to access receive

Failed to communicate with "/calibre/interface-data/init?1547580343661", with status: [502] Proxy Error

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> 502 Proxy Error
Proxy Error
The proxy server received an invalid response from an upstream ser

This leads me to believe there is some issue with the way my reverse proxy is handling the request.
Thank you for any and all assistance, let me know if there is any additional info I can provide!
