Getting "returnToUrl" in TruClient script playback, but works OK manually

Hello,

I have an application which takes a user/password login.  I can do it manually and I have successfully recorded a script that logs a user in.  But, when I play the script back, it returns to the login page with a "returnToUrl."

Some details:

FireFox (52.0.1 (32-bit)

LoadRunner 12.53

HTTPS is enabled

Any clues about getting around this?

Thanks
