That's always sad when it happens! Sorry for your loss! I'm no expert on networking things -- I'm sure someone with more experience will be along.
Ordinarily when you get errors under node a big yellow error message will pop up on screen. My guess is that using apache as a proxy blocked those messages. That is, apache got the messages but didn't pass them to the browser. That suggests there might be some tweaking of the apache proxy that is required. Hopefully someone with experience with apache can help. If you had noticed before shutting down the server, you could have saved your changes. Use the advanced search, filter tab and type [haschanged[]] Then use the download icon to save all the tiddlers to your local file system in a JSON file. Later, when the problem is fixed, drag and drop the JSON file back into your server. Good luck!
