My application running on Windows 10. But on Windows Server 2012 gives this error. How can i fix this error? What could be the reason for this? Thanks... (Filename: C: \ buildslave \ unity \ build \ Modules / UnityWebRequest / Implementations / TransportCurl.cpp Line: 760) Curl error 35: Handshake failed. UnityTls error code: 7
cURL error 35 is a common SSL/TLS failure that can have many causes with no simple answer. However, the "Handshake failed" detail could indicate incorrect Certificates, either on your side or the remote server. Since the error doesn't occur on Windows 10, probably means your Server 2012 instance isn't configured properly. Here's a link to a blog that covers this SSL handshake failures in detail: https://www.thesslstore.com/blog/tls-handshake-failed/ to help you troubleshoot. Also, here's a link to another Unity forum thread about a similar (but not the same) issue, it's specific to the Editor but may be of help: https://forum.unity.com/threads/iap-crashes-unity-with-unitytls-error-code-7-in.787847/
