I've downloaded Sage 6.3 from AUR, and it works OK in terminal, but I can't connect via browser:

~> sage
│ Sage Version 6.3, Release Date: 2014-08-10                         │
│ Type "notebook()" for the browser-based notebook interface.        │
│ Type "help()" for help.                                            │

It opens browser, but there I get "Connection Refused" message and white screen. I'm running 64bit Arch Linux. Any ideas?

Could you be more precise on the message in your browser? On the other hand, do you have a firewall?

I get no message at all in the browser, there simply is no response at the port where the notebook shall listen. And no, I have no firewall nor antivirus or anything that could interfere.

Are you sure that the port is actually open? Could you check with nmap or similar tool? If there is no firewall, it looks like your browser refuses the connection. Did you check with different browsers?
