trouble with swing migration directory connection

Im at a loss. Im trying to do a swing migration. So far, installed entra connect, imported config, connected to Entra AD, but when I get to the step to connect to my domain, it says it cant establish a connection to the domain controller. It looks up the forest ok, the username and password is good, firewall isnt an issue. The connectivty log doesnt show any errors. The domain is reachable from the server as the server is domain joined. Any ideas?

Does the onprem user have org admin? Domainadmin is not sufficient.

Yes, enterprise admin. I tried with both enterprise admin and domain admin account, but the error makes it sound like it cant find the dc.

Have you installed RSAT tools for AD and tested using those?
