Thanks for your answer Mike,
FIPS mode only accepts TLSv1. It also rejects SSLv23 handshake. You may wish to either enable or disable FIPS on both ends.
so enabling fips on PCB "fips = yes" drive to an this error : Line 10: "fips = yes": Specified option name is not valid here
in other hand, disabling fips "fips = no" drive to the same error Line 10: "fips = no": Specified option name is not valid here
where do I need to put it ?
I have tried to disabling fips on PCBA and set at both end "sslVersion = SSLv3" but same result as when I had "sslVersion = TLSv1"
PCB log : Mar 19 15:04:55 server stunnel: LOG5[7789:140610069133056]: Error detected on SSL (read) file descriptor: Connection reset by peer (104)
any idea ?
Best
