Hi, Dheeraj, Are you testing the connection with Telnet? Or are you testing with the application. What I noticed in testing the connection is that once the command is completed, the connection is closed.
However, when I test from my application, its only closed once all transactions in that session are completed, and will show how much data was passed on (following from my logs at the end of a non-telnet test session. 2017.06.13 10:16:08 LOG6[1]: Negotiated TLSv1.2 ciphersuite AES256-GCM-SHA384 (256-bit encryption) 2017.06.13 10:16:18 LOG6[1]: Read socket closed (readsocket) 2017.06.13 10:16:18 LOG6[1]: SSL_shutdown successfully sent close_notify alert 2017.06.13 10:16:18 LOG6[1]: TLS closed (SSL_read) 2017.06.13 10:16:18 LOG5[1]: Connection closed: 2791 byte(s) sent to TLS, 1641 byte(s) sent to socket Liz Turi Sr. Consultant Massachusetts eHealth Collaborative 860 Winter Street, Waltham, MA 02451 (m) 339-222-6614 (o) 781-907-7204 (f) 781-207-8589 www.maehc.org<http://www.maehc.org> [fb_icon]<https://www.facebook.com/massachusettsehealthcollab?fref=nf>[li_icon]<https://www.linkedin.com/company/massachusetts-ehealth-collaborative?trk=tyah&trkInfo=clickedVertical%3Acompany%2Cidx%3A1-1-1%2CtarId%3A1432746657126%2Ctas%3AMassachusetts+eHEalth>[tw_icon]<https://twitter.com/MAeHC_org> From: stunnel-users [mailto:[email protected]] On Behalf Of Dheeraj Gautam Sent: Tuesday, June 13, 2017 11:41 AM To: Małgorzata Olszówka <[email protected]> Cc: [email protected] Subject: Re: [stunnel-users] Stunnel Connectivity Issue HI Guys, below is the config which i have configured with TLSv1.2, but still connection establishing only for while when i telnet telnet 127.0.0.1 9233. and just after connection closed.

Although, stunnel logs indicating that configuration successful, but in logs no where is mentioned about the connection is it connected or not, Hello Dheeraj, You should set the verifyChain option in order to verify the certificate stored in the file specified with CAfile: verifyChain = yes Then you can test your connection: telnet 127.0.0.1 9233 the stunnel logs will show information about the connection attempt.
