Unfortunately, the calibre debug log doesn't contain content server information. That info is in a different set of logs. My apologies -- I forgot.
Could you send me the logs that you see by going to Preferences -> Sharing over the net and clicking the "Show server logs" button? Please send both logs.
And to be precise, it now works where the only thing you did was to change the column title (not the lookup key) back to what it was, then restart calibre? Did the title that didn't work have any unusual characters in it, for example a '&'?
