Unity iOS WWW POST failing ssl handshake
I'm attempting to retrieve a token from a REST endpoint in an iOS app, but I'm getting an error in my SSL handshake. The error, as seen in Xcode's output logger is below

@juan_arias Did you find an answer to this issue? I am having the same error in Unity 2018.3.8 on an iOS build.,Is there an answer for this issue? I am seeing the exact same thing. Unity 2018.3.8
@juan_arias this could be an issue with your end-point. I am not sure what your endpoint is, but what happens when you try to access it through Postman for example?
Works fine through postman and even on Android build. This is a microsoft login end point.
A lot of Windows-based endpoints use NTL$$anonymous$$ or (even worse) NTL$$anonymous$$v2 authentication. It may be the case that the iOS web request libraries simply don't support that type of authentication.
At a $$anonymous$$imum, check your player settings and make sure you're not using .NET 2.0 Subset - I've found the subset version doesn't include all authentication methods, while the full version seems to.
If you've got any control of the server, check group policy. Some servers are configured to insist on NTL$$anonymous$$v2 authentication, which isn't all that compatible with non-$$anonymous$$icrosoft solutions. If you've got the chance to allow earlier versions of NTL$$anonymous$$, it may help.
@Juan_arias & @kambrusterxstud Try using UnityWebRequest instead of WWW. This solved an SSL issue for me before.
Thanks for the help. We are using UnityWebRequest.
I've found this thread and have been working through it. Will post with results.
Cool, good luck and let us know how it goes.
