Cannot log directly into an esxi host using a newly created user account

I have an esxi host running version 6.0. I logged directly into the host as root through the web client, added a new local user from the Security & Users tab, and assigned that user the Read-Only role from the permissions section. When I attempt to log in to the web client as the new user, it spins for a few seconds and says that the connection timed out. If I try through the desktop client, it hangs on loading inventory for a few minutes and gives a similar timeout message. If I log in as root from the exact same computer, it works. Am I missing something?
