Local calibre OPDS response code 400

[sat3ll]

• KOReader version: 2019.11
• Device: Android | Kindle Fire HD (2nd Generation) (2012)

Issue

Attempting to use a Local calibre catalog results in "Cannot get catalog. Server response code 400"

Steps to reproduce

• Have calibre start a OPDS server (with user/pass config)
  • Tested on localhost and another device in the same LAN via web-browser
• Set host/port/user/pass in KOReader.
• Attempt to connect

I've also tried to "Add new OPDS catalog" with almost the same settings but appended '/opds/' in the
catalog URL.

Calibre server logs indicate that there are attempts to retrieve/access it but with error 400.

192.168.0.143 port-51127 - 22/Dec/2019:23:14:09 +0000 "HEAD /opds HTTP/1.1" 400 126
192.168.0.143 port-51128 - 22/Dec/2019:23:14:09 +0000 "GET /opds HTTP/1.1" 400 159

Quite possibly a duplicate of #3953

#3953 mentions no error message but I decided to try some settings based on that ticket:

• Disabling user/password auth = Works
• Enabling user/pass auth with auth=auto = Error 400 (even with no user/pass specified)
• Enabling user/pass auth with auth=digest = Error 400 (even with no user/pass specified)
• Enabling user/pass auth with auth=basic = Works

It's likely that this issue is actually a "progress" of the issue #3953 that you mentioned.

@sat3ll: that info is quite relevant. Lets move converstation to #3953.
