You might want to take a look at the following article for running a test against multiple environments
using the BaseUrl feature if that is what you are going after.
If this doesn't help, could you please share your test files and also provide your test failure logs (there should be at least 3 files in the export). You can export these to file
from the failure tab of your test and add them to a .zip. These files can help us determine better what was the reason for the failure of your test.
Looking forward to hearing from you.
