Cannot access Content Server - even locally

[BumbleBernie]

Running Calibre 1.26, Windows 7 Ultimate 64 bit

When trying to connect to Content Server using Firefox locally on the PC I am getting the error:

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Traceback (most recent call last):

Any help appreciated,

does it work when you click test in the options section?

Just in case someone else might have a clue what is going on: that error is raised because there is an attribute in the HTTP request named "wsgi_environ" and that attribute has an invalid value. I don't know why such an attribute might exist.

Possibilities I can think of:

• calibre is running behind a reverse proxy that uses a WSGI module.
• cherrypy is looking at some environment variable that sets up WSGI.
• there is something installed that is getting between the network and calibre, adding attributes to the request. "Something" would most likely be some kind of security software.

@BumbleBernie: does the problem go away if you boot in "Safe Mode with networking"? That mode should remove any extra software that might be getting in the way. If it works, then at least you have some information about what you might need to look for.

Kovid recently added a statement to the Documentation that using the in-process server (with WSGI) is not a good idea (if that is what you are doing):

The calibre content server can be run directly, in process, inside a host server like Apache using the WSGI framework.

[BumbleBernie]

@Glorfindel: Sorry, don't know what TEST you mean.

@chaley: No reverse proxy
cherrypy - I am only using Calibre, nothing else
Firewall on or off, no antivirus - same error
Starting Windows in safe mode with networking - same error

@eschwartz: I am only using Calibre (connect/share options), nothing else

Thanks for your responses - I am still stuck

when you open the settings area of the content server (under preferences )where you can set it up and turn it on there is a button that says test server or something like that, you can also test it manually by typing in the following in a web browser: 127.0.0.1
I think that's what it is any way...

127.0.0.1:{whatever port you are using, default is 8080}

Clicking "Test Server" is definitely a much better option -- it will open the URL directly, passing it to your browser.

[Glorfindel]

yeah thats right... forgot about the port #

[BumbleBernie]

Selecting TEST SERVER produces the same error.

What environment variables do you have defined?

The easiest way to get a list of environment variables is to open a command prompt then type "set" (no quotes) then return.

Those are the environment variables set:

I am very close to out of ideas.

One thought: what language is calibre set to, and what is the language of the PC? If calibre is not set to English (which I expect it is not), does changing its language to English change the behavior? I am wondering whether there might be some character encoding issues.

[BumbleBernie]

Calibre is set to English

[chaley]

I don't think it matters, but for completeness: what language is the computer using?
