If you click on the API link “ping” in the QSDA Control panel, do you get a response?

Yes
{“serviceName”:“Qsda.Service”,“workingSetSize”:110436352}

Please try the following:

What error do you get from ?
localhost:5003/serverconnection

raghu · July 20, 2023, 9:36am

It was blank screen, checked this in console log:
blazor.server.js:1 [2023-07-20T09:32:40.692Z] Error: There was an unhandled exception on the current circuit, so this circuit will be terminated. For more details turn on detailed exceptions by setting ‘DetailedErrors: true’ in ‘appSettings.Development.json’ or set ‘CircuitOptions.DetailedErrors’.

rob · July 20, 2023, 3:38pm

When you refresh the screen, what errors do you get in the error log? The message
Error Could not find a part of the path ‘C:\ProgramData\EasyQlik\QSDA\qsda-apikey.json’.
should not reappear. QSDA should have recreated the qsda-apikey file. Can you check?

Did you delete the entire QSDA folder? It looks like it’s failing trying to decrypt something in that folder.

raghu · July 26, 2023, 2:09pm

Yes and getting this error in qsda-errorlog:

Did you install for “all users” or “only for me”?

I recommend you

uninstall QSDA using Windows Programs and Features,
Delete folder C:\Program Data\EasyQlik\QSDA
Delete folder C:\Users*userid*\AppData\Local\EasyQlik\QSDA
4.Install the latest QSDA, 2.5, available here: Download QSDA Pro - EasyQlik

If you still have difficulty please let me know:

If you installed “for all users” or “only for me”.
Screenshots of the above two folders,
