I'm trying to set up a Sync server. I have a linux box running the AUR package for arch. I setup sync.conf to http://192.168.x.x:5000/, and followed the instructions found on this page: https://wiki.archlinux.org/index.php/Mozilla_Sync_Server The server appears to start without issue, although I don't know how to turn on a verbosity. On a separate machine, I bring up the sync dialogue, enter my email, and a password. However, upon trying to enter the server (identically to what is above) it will show the red error symbol and ask for a valid server URL. No matter how I tweak what I have entered, the message doesn't go away unless I re-select custom server in the drop down. I'm not sure if it's an issue or not, but with the recaptcha, if I hit enter after typing in the words, it just resets... Thanks in advance for your help.
