When users get a 500 error when trying to log in to the SESWeb server, first double check that SDConnex is still running.
If that's checked/restarted, you can also try to decode the 500 Error text string using a Windows command prompt.
For customers who cannot connect to the web to access https://www.base64decode.org/ to interpret the error message:
Run the following to decode the 500 Error's base64-encoded text to regular text:
Steps:
1 - Copy/save the 500 Error message text into a text file.
2 - Navigate (cd) to the location where you saved the text file from step 1.
3 - Run:
Certutil –decode encodedInputFileName decodedOutputFileName
e.g. If you saved the copied error text into a file (say) named base64.txt, the command will look like this:
Cd \destination\
Certutil –decode base64.txt decodedbase64.txt
4 - Open the result file (decodedbase64.txt in the example) in a text editor or Notepad to find out what error was thrown by the SESWeb server.
