Could be the versions of communication are different – from SSLv3 to TLS1.3 …

Having said that, there is NO REASON to use stunnel and a VPN – both encrypt data.  You only need to encrypt it once … so I’d change your software to behave differently via VPN or not.

Subject: [stunnel-users] No more addresses to connect

I am trying to implement an openvpn + stunnel vpn with a Linux host server and a windows client, i have everything connecting when alone but when I connect openvpn over Stunnel i get and error that says:

2019.01.07 21:18:50 LOG5[0]: Service [openvpn] accepted connection from 127.0.0.1:49343

2019.01.07 21:19:15 LOG5[1]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket

2019.01.07 21:19:20 LOG5[2]: Service [openvpn] accepted connection from 127.0.0.1:49380

2019.01.07 21:19:30 LOG3[2]: s_connect: s_poll_wait 74.215.118.189:1194: TIMEOUTconnect exceeded

2019.01.07 21:19:30 LOG3[2]: No more addresses to connect

And this error will loop until I disable the openvpn connection.

Any help would be appreciated.

Thanks
