I was building apps with xamarin.forms before for a while, and of today: the first time my app connects to our API the app halts on no specific line stating:

 tls support is not available 

I have changed nothing on my app, especially not in regard to the tls support.

Is anyone else having this issue?

This is the whole error message:

I have also noticed that the system generats a new file called_ mono_crash-json

its a long file like this:

{
  "protocol_version" : "0.0.6",
  "configuration" : {
    "version" : "(6.12.0.158) (2020-02/5ce143a1a88)",

 },

CodePudding user response：

As it turns out, enabling the linker and NOT setting it to "LINK NONE" solved this issue. For some reason, with a disabled linker, the linker must have removed libraries that were needed for the TLS support...
