I'm having a problem licensing a copy of ArcGIS Pro on a computer. Through myesri, I created a new single-use license and emailed it to the end user. She opened it up on her computer through email and ran through the process to authorize it, but is getting an error about not being connected to a licensing portal. Has anyone had this problem? I've had her log in as a named user and that works fine. I had her restart, but she keeps getting the same error when she tries to authorize through the license I created for her. Any idea what might be going on?
