Hey there,

Ubuntu switched to openssl3 by default for its incoming LTS and we 
started received reports that connect to PEAP wifis isn't working for 
some users. Our version of wpa is 2.10

One such report,

The wpa is coming from Debian without change and an user reported that 
installing the Debian build (which is still using openssl1) doesn't have 
the issue

The log has those errors

wpa_supplicant[648]: SSL: SSL3 alert: write (local SSL3 detected an 
error):fatal:internal error
wpa_supplicant[648]: OpenSSL: openssl_handshake - SSL_connect 
error:0A0C0103:SSL routines::internal error
wpa_supplicant[648]: wlp4s0: CTRL-EVENT-EAP-FAILURE EAP authentication 

A debug log is available on
