Authentication issue unsupported protocol


I am trying to connect my esp32 device to an enterprise network which uses freeradius version 3.0.20 and i am encountering unsupported protocol issue as in the log below. However, my phone can connect to the same network. Also, my colleague (unfortunate we are working apart as we are working remotely) was able to connect the same device but he is using the version 2.2.8. What could possibly be the cause of the issue and how to resolve it?

(2) Found Auth-Type = eap
(2) # Executing group from file /etc/freeradius/3.0/sites-enabled/default
(2)   authenticate {
(2) eap: Expiring EAP session with state 0xe0953071e1962993
(2) eap: Finished EAP session with state 0xe0953071e1962993

Thank you so much!
