HELP!! Unable to launch any notebooks

I'm getting an error for 503: Proxy Target Missing when I go to open any of my existing notebooks or start a new one.

Just keeping the notebooks open lands me in the tarpit every day before I log in, and I thought that may have been an issue. So yesterday I deleted all ongoing processes and hoped it work today. It did not.

I also feared my file was corrupted, but everything was still there when I downloaded and opened with notepad.



Looks like our server got confused about what was running and what wasn't. I think I've sorted that out now, so try again and let us know how it goes.

Works like a charm!

Great! Thanks for confirming.
