I'm trying to link my org AGOL site to our on prem Portal site via the Distributed Collaboration model. I've set up everything in AGOL such that I get the invite file at the end of the process. I then attempt to open that invite within my on prem Portal site and I get the following error: "The chosen invitation file was intended for another recipient. Please choose an invitation for your organization." I can't figure out what is wrong. I've checked the guest and host URL in the invite file and they both seem correct. If I paste the guest URL that is in the invite file into my browser address bar, our Portal site comes up as expected. The URL is in the form https://mysite.mydomian.org/arcgisportal where "arcgisportal" is my configured web adapter for our Portal site. What am I doing wrong with this?
