API Error 0 when starting optimization with AIMMS Pro

I’m trying to run an application via AIMMS Pro/WebUI. I can run the optimization via AIMMS Developer/WebUI without a problem, but when I try the same on the AIMMS Pro server the following error-message appears:


awf.data.aimms.session: Running procedure 'testprocess' has resulted in an error: API Error 0 when running procedure 'testprocess': (code=500)


Can anyone help me with that?


Best regards

Hi Jonathan, 

Can you send us an e-mail with the PRO logs (for PRO on premise) or the time stamp when you tried to start the app (for PRO on cloud) so we can check where the problem is. 

Thank you!
