Hi,

[quote user=""]When calling connect() function, occasionally we get "TLS handshake error: -0x2700" message followed by connect returning 113.[/quote]

Is it that there are sometimes no problems when you try to connect?

How often is occasionally? Is there anything that might trigger this issue that you are aware of?

Is the issue reproducible on your end?

Can you provide complete error log?

Best regards,
Dejan

Hi Dejans,

we're using a custom certificate and a custom server, so this change shouldn't impact us. I'm sorry - I should have mentioned that before.

Thanks,

Hi,

You could try to use new CA certificate as shown in this pull request.
