TLS version used by JOSE (JWT)

We are ‘suddenly’ getting “socket error #10054” from our JOSE application.

The SSL libraries used are definitely TLS 1.2 capable.

‘They’ are telling us it is because TLS 1.0 and 1.1 are no longer supported, but in the code that was supplied by a third party there is no I/O handler set for IdHTTP.

Is this defaulting to something other than the maximum?
