Two Apps Suddenly Are Unable to Load Data

Question

Hello,
This problem may or may not be from LightSwitch.  I have two apps on Azure websites, with Azure DBs.  One has been working great since deployment, about 10 months ago.  The other has been working well since Nov.  As of today, both
are unable to run their queries or load data. 
Nothing has changed on our end and I am getting so many different error codes, but the gist is that they are unable to connect.
I've checked both databases and they are working.
I've noticed one error message that says the URI http://site.azurewebsites.net//ApplicationData.svc/etc is not valid because it is not based on http://site.azurewebsites.net/ApplicationData.svc/
Does anyone else have a production app this has happened to?  Or know how to get those URIs matching again? Any help would be greatly appreciated!
Thanks,
C

Hi Chris
You'll notice below that David Ebbo has assisted in trying to get my site up and applied a work-around but it hasn't fixed my issue.
He's had to leave the office so I'm trying everything I can think of to get my site back up.
You can read the details in my discussion with him further down in this topic.
I'm just stabbing in the dark but my HTML client gives this error "Request failed with status code '400' and status text 'Bad Request'" and in the forum I find that someone also experienced the issue at this topic:

A proposed solution on the thread is:
"In my case after upgrading the project to the March 2004 Lightswitch format and getting this error I had to install this nuget package to make it work on the server:
https://www.nuget.org/packages/System.IdentityModel.Tokens.Jwt/"
Should I go down this path or is it a red herring?
Thanks, Mark.
PS: My SL client gives this error on loading the first screen:
"An error occurred while running the screen. Error details: Exception has been thrown by the target of an invocation."

Woo Hoo. I went to Cloud Cellar and recovered files only from my backup and now my HTML client works :-)
My SL client gets all the way past loading nearly all the initial screen data then comes up with this error:
"The metadata URI 'http://login.skemaz.net/ApplicationData.svc/$metadata#Chains' references the entity type with name 'LightSwitchApplication.Chain'; however, the name of the expected entity type is 'LightSwitchApplication.ChainsTemp' which is not compatible
with the entity type with name 'LightSwitchApplication.Chain'."
We seem to be getting somewhere.
Please assist with the above. Thanks, Mark.
