Punjab fails on localhost (500 Internal Server Error), using Strophe.js

[HyprGeek]

Using Strophe.js to initiate a connection.

Running punjab on Windows 7 64-bit, using python 2.7 64-bit and installed other dependencies (win32 api as well).

Added proxy to apache server
(in httpd.conf)
ProxyPass /bosh http://localhost:5280/http-bind
ProxyPassReverse /bosh http://localhost:5280/http-bind

Calling http://localhost/bosh in browser returns XEP-0124 - BOSH.

When connecting to http://bosh.metajack.im:5280/xmpp-httpbind, it works both using the url and the proxy.
ProxyPass /bosh http://bosh.metajack.im:5280/xmpp-httpbind
ProxyPassReverse /bosh http://bosh.metajack.im:5280/xmpp-httpbind

What version of python? It may be a recent bug in twisted with python 3.

http://twistedmatrix.com/trac/ticket/6245

[HyprGeek]

Hi,

I've mentioned it in the previous post,
"Running punjab on Windows 7 64-bit, using python 2.7 64-bit and installed other dependencies (win32 api as well)."

I uninstalled python and related stuff, and reinstalled python 2.7 32-bit and the dependencies (32-bit). Still does not work.

I searched on the net, and it seemed like DNS problems...I added the following line in punjab.tac
Code:
bosh.connect_srv = False

Now, the call goes on forever, and I'm stuck with connecting stage in the app.

The bug mentioned by @twonds is indeed the cause here, as the SRV lookup fails, for Twisted 12.3.0. The fix is now in review, and hopefully we can get a bugfix release 12.3.1 for it.

[HyprGeek]

Oh, then I'll use an older version of Twisted while the bugfix is underway. Thanks a lot @twonds @ralphm.

[HyprGeek]

Just wanted to post an update. I used Twisted 12.2.0, and punjab is working fine now.

[ralphm]

@HyprGeek you might want to check this workaround. Obviously it doesn't work with IDN domain names, but it never did before. As it is really an application issue how to work with IDN domain names, I did resolve that in Wokkel.

Hi Im seeing a similar issue,
My reuest will be received by punjab, it will get the response stream from openfire , but the same stream is not sent to the client and this doesnt let the user login complete.

Im using punjab with twisted 14.02 version.

Below is the log

Any help would be of great favour

[twonds]

I do not see an error in the log provided. Can you include the error? Also, it looks like this may be a separate issue than the issue here because Punjab is making an attempt to connect. Do you mind creating a new issue or sending an email?
