I believe you restored a WFA3.0 backup file from a WFA server on one windows machine to WFA3.1 on a different machine. Correct?
Every WFA installation on a windows machine has a unique key, which is set during installation time. Subsequent installation on same windows machine will not generate a new key but retain the one created during the first installation.
When you restore a backup from one windows machine to another one, the other machine has a different key and the key isn't transfered ( Its is transfered with source being WFA3.1 which allows a FULL backup) . And hence the saved credentials and Data Sources do not work on the new windows machine with new WFA.
What to do?
You need to transfer the key from Old WFA3.0 windows machine to WFA3.1 machine. How to do that? Its available on WFA Installation and Setup Guide.
If you can't find it, I'll post here for it.
If you have wiped off your old WFA. Then on your new WFA windows machine. Do the below:
1. Open every single credential and re-save it.
2. Open every single Data Source and re-save the credentials.
