We are working on adding support of IPv6 to our embedded device the connection is established to ipv6 server with 80 port successfully. Now, while connecting with wolfssl with 443 port we are facing the error issue -188 "ASN no signer to confirm failure"

We have also implemented the following step from readme file
"Note 2)
wolfSSL takes a different approach to certificate verification than OpenSSL does. The default policy for the client is to verify the server, this means that if you don't load CAs to verify the server you'll get a connect error, no signer error to confirm failure (-188).

If you want to mimic OpenSSL behavior of having SSL_connect succeed even if verifying the server fails and reducing security you can do this by calling:

wolfSSL_CTX_set_verify(ctx, SSL_VERIFY_NONE, 0);"

After adding this command we are getting the error -112 "mp_exptmod error state"

Please guide us if there is anything we are missing? I have also added the logs..
