We are trying to migrate our servers. When trying to use Join Site for Portal, it gives errors about unable to generate token or the url is inaccessible.
Our portal admin site is https://webgis.domain.com:7443/portal/portaladmin, but it keeps trying to change portal to use https://webgis.domain.com:7443/arcgis/portaladmin.
I have double and triple check the Admin username and password is correct.
I have attached the error log.
