Hi guys!
I’ve been able to fix this issue by combining my cert and key into p12 file with:
openssl pkcs12 -export -out workingCertAndKey.p12 -inkey privateKey.key -in certificate.crt
It must be some kind of problem with my private key. What is strange that on other distributions my files work correctly so it’s probably some problem with openssl/wpa_supplicant.
