Hostname issues - Githubissues

Hi,

I can successfully authenticate with trakt, but immediately after, I get this error. I also get it on subsequent launches when it is loading the saved authentication. I made sure my /etc/hosts file had $HOSTNAME assigned to 127.0.0.1. Any other suggestions?

Here is the output of the dns-sd command:

$ dns-sd -B _mediaremotetv._tcp local

Additionally, nmap shows the Apple TV host/port as open.

That looks like it worked. It asked for a code and displayed on the Apple TV. I hit a few errors after that step though. The first time I ran:

# python tvscrobbler.py

    res, self.input_nonce = self.do_encryption_operation(self.input_key.decrypt, data, self.input_nonce)

Then I killed it and tried again. They are different the second time for some reason:
