Hi @CoolDevGem ,
The failure is most likely due to inability to negotiate a cipher suite, or TLS protocol version between client and server.
That server supports only the following Perfect Forward Secrecy AEAD cipher suites, so if your client doesn’t support them, it will fail to negotiate:
# TLS 1.3
# TLS 1.2
That server also only supports TLS 1.2 and TLS 1.3 - so if your client doesn’t support those - it will fail.
- the cryptographic library used by the client is too old and doesn’t support these, or
- the cryptographic library system-wide TLS configuration hasn’t enabled these, or
- the client’s TLS configuration hasn’t enabled these.
