Problem with EAP PEAP Authentication on freeradius 3.22

[Gleb Lisikh]

Hello world!

Trying to enable EPA2 Enterprise authentication for a Cisco Meraki  AP.
EAP Authenticaton section fails with the following:
=====================================
(2) eap: Peer sent EAP Response (code 2) ID 2 length 161
(2) eap: Continuing tunnel setup
(2)     [eap] = ok
(2)   } # authorize = ok
(2) Found Auth-Type = eap
(2) # Executing group from file /usr/local/etc/raddb/sites-enabled/default
(2)   authenticate {
(2) eap: Expiring EAP session with state 0x1da40b4e1ca6122b
(2) eap: Finished EAP session with state 0x1da40b4e1ca6122b
(2) eap: Previous EAP request found for state 0x1da40b4e1ca6122b, released
from the list

(2) eap_peap: ERROR: System call (I/O) error (-1)
(2) eap_peap: ERROR: TLS receive handshake failed during operation
(2) eap_peap: ERROR: [eaptls process] = fail
(2) eap: ERROR: Failed continuing EAP PEAP (25) session.  EAP sub-module

(2) eap: Sending EAP Failure (code 4) ID 2 length 4
(2) eap: Failed in EAP select
(2)     [eap] = invalid
(2)   } # authenticate = invalid
(2) Failed to authenticate the user
=====================================

Any idea where I may need to start troubleshooting? I haven't touched
Authentication at all from its original. Authorization is done through
python3 and seems to be working just fine.
By the way, exactly the same error occurs on a different freeradius server
running 3.021

Thank you!
