Thanks. They use TLS1.2. I've found a partial solution. I've added, to my root certificates PEM file, Chorus serveur-side certificates (AIFE certificates). It's not an optimal solution, because i must update this file each 2 years. If i use SoapUI to communicate with ChorusPro, i only need my certificate. So i will try later to find a solution to do the same with ICS.

With ICS 8.61, i'm trying to connect to french rest API called "Chorus PRO" (https://chorus-pro.gouv.fr:5443), with : - HTTP Rest Demo sample - TLS1.2 - Auth : Basic with login/password - client p12 certificate; When i try to connect, i've this error (end of log output) : ProtoMsg: None, State: SSLv3/TLS write finished, Send, DataLen: 5, Data= 1603030040 ProtoMsg: TLS 1.2 Handshake: Finished, State: SSLv3/TLS write finished, Send, DataLen: 16, Data= 1400000C8754B071224385E797740416 01F41D90 ICB> SSL_connect: SSLv3/TLS write finished 01F41D90 TCustomSslWSocket.Do_FD_CLOSE error #10053 handle=1008 01F41D90 *CloseCalled handle=1008, State=SSLv3/TLS write finished (TLS_ST_CW_Finished), Err=error:00000000:lib(0):func(0):reason(0) 01F41D90 SslHandshakeDone(1) Handle=1008.
