Hi @ABhanawala ,

I've seen similar scenarios.

The logs indicate that the portal authentication fails with the error auth-failed-invalid-http-arg.

This happens because the device hostname contains spaces or special characters (such as apostrophes), which the firewall rejects as invalid computer input during the authentication check.

For example  (Kiwi's Macbook Air),(Jon’s MacBook Pro (2)), which contains spaces or special characters (such as apostrophes).

In this scenario, changing the macOS device hostname to a simple string without spaces or special characters (e.g., KiwisMac or JonMacPro) fixed the issue.

The Reddit post you shared also leaned towards a special character issue.

Best,
