Check what it’s been authorized for on the switch.

I had a similar issue with my Extreme switches, where it would authorize them, 
but wouldn’t return a VLAN. I had to get clever with my interface tagging.

Good luck.

Try this command:
Show dot1x <brief | detailed> <interface interfaceName>

I got this from here:

Subject: [PacketFence-users] Voip AND 802.1x on Juniper switches

❗External message: Use caution.
We have set up packetfence but we still struggle with voip.
That is we nicely get our phones to get LLDP parameters but it stucks when 
trying to connect to provided the voip server.

The logs say:

On the switch (Juniper EX2300) I can still see

Interface     Role           State           MAC address          User
ge-0/0/2.0    Authenticator  Connecting      08:00:0F:E4:16:04    No User

It looks like that no voip tagged packet get across the switch, that continues 
to try to authenticate via 802.1x.

Any hint?

Tanks a lot in advance,
G
