Access denied in selection list and resource credentials but backups run fine

When looking at a user-defined selections list and trying to expand any server I get an invalid credentials error and it asks me to select a user to attempt to try again with. When using the Resource Credentials tab, all the servers except the backup server I'm on fail the credential test. 

But the crazy thing is the backups work fine. This just happened one day when I went in to add a server to the selection list. The credentials and permissions are correct and like I said backup jobs are running just fine on the same backup server with the same credentials backing up the same servers in the same selection list.
