Hey guys. I'm having trouble using the Certificate in my BO. It started to occur after updating the certificate. I have 2 configurations and 2 certificates, the first one was updated and no error occurs, the second one, the  bad certificate or Handshake failure errors occurs. Both have the same configuration. I already tried marking SSLV3, handshake error occurs. When I unchecked it, a Bad Certificate error occurs. Do you know what I can do in this case to solve it?I looked for some threads in the community, and I didn't find a solution for my case. The Certificate works correctly on other systems and platforms. My Intersystems IRIS version is 2018.1 Errors: ERROR #6085: Unable to write to socket with SSL/TLS configuration 'GNRE\_PRO', error reported 'SSL/TLS error in SSL\_connect(), SSL\_ERROR\_SSL: protocol error, error:14094412:SSL routines:ssl3\_read\_bytes:sslv3 alert bad certificate' ERROR #6085: Unable to write to socket with SSL/TLS configuration 'GNRE\_PRO', error reported 'SSL/TLS error in SSL\_connect(), SSL\_ERROR\_SSL: protocol error, error:14077410:SSL routines:SSL23\_GET\_SERVER_HELLO:sslv3 alert handshake failure' ![](/sites/default/files/inline/images/images/image(5749).png) log generated by REDEBUG 03/09/23-13:32:46:095 (14200) 0 [Generic.Event] tpopen for host www.gnre.pe.gov.br device number 49926342 port 443  mode 0x8848 tcpmode 0x24 terminators  ibfsz 8192 obfsz 8192 queuesize 5 timeout 5 tcpsbuf=0 tcprbuf=0, XY=off, BINDTO= 03/09/23-13:32:46:095 (14200) 0 [Generic.Event] TCPConnect: SNDBUF sys size=131072, dev size=0 03/09/23-13:32:46:095 (14200) 0 [Generic.Event] TCPConnect: RCVBUF sys size=131072, dev size=0 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  TCP connected to site 200.238.99.68 port 443 03/09/23-13:32:46:158 (14200) 0 [Generic.Event] StreamInit: SNDBUF sys size=131072, dev size=0 03/09/23-13:32:46:158 (14200) 0 [Generic.Event] StreamInit: RCVBUF sys size=131072, dev size=0 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  SSL/TLS configuration: GNRE_PRO 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  Cipher list: ALL:!aNULL:!eNULL:!EXP:!SSLv2 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  Certificate file: E:\Progress\Certificados\ClienteCert.pem 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  Setting private key file encryption password 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  Private key file: E:\Progress\Certificados\privateKey-decrypted.key 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  Peer verification option = 0, certificate depth = 9 03/09/23-13:32:46:158 (14200) 0 [Generic.Event]  SSL/TLS client requested. 03/09/23-13:32:46:220 (14200) 0 [Generic.Event]  SSL/TLS error return from SSL_connect(). 03/09/23-13:32:46:220 (14200) 0 [Generic.Event]  SSL\_ERROR\_SSL: protocol error 03/09/23-13:32:46:220 (14200) 0 [Generic.Event]  error:14077410:SSL routines:SSL23\_GET\_SERVER_HELLO:sslv3 alert handshake failure 03/09/23-13:32:46:220 (14200) 0 [Generic.Event]
