Hub Decision - Something went wrong

BohyonHwang
Level 9
Hi there.
I need some help to solve a problem.

After installing Decision, I selected the Decision menu in Hub in order to test the training .
“Something went wrong” message appeared in the upper right corner.
Afterwards, In spite that Define, Train, and Calibrate actions were performed, but the final learned model could not be saved.

First of all, I need to solve this problem of “Something went wrong” message.
Message does not give any good information to solve.
I looked into several directories and found an errors file for Hub.

A brief is as follws.

This product required all the logs available. The best way to help you is to open a ticket with our technical support team.
Please provide your version of HUB and Blue Prism.
Please include all the logs from the following folder in a single ZIP file. Like in the following example:

I was facing the same issue, steps to resolve: double check you've added the iis_iusrs group to the certificate created and ensure that in your hosts file there is an entry for your decision URL - with our install the hosts file entry wasn't there leading to the above errors
