Hello, I have trouble with stunnel on Android 7.x.. I'm trying to connect to OpenVPN server through SSL tunneling with stunnel. On phone I'm using stunnel installed in Termux and OpenVPN. Everything is correctly configured, Im using the same config on other devices in same network and it works perfectly. I tried it with different devices with Android 7.x and it is not working at all :(

Immediately after succesful connection I am receiving: TLS fd: Software caused connection abort (103) TLS socket closed (SSL_read)

And it is still reconnecting again and again with the same error. I also tried it with stunnel downloaded directly from stunnel.org site..

Anyone with new Android who have working stunnel? Where can be the problem?

Example stunnel.conf on Android: socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = debug [openvpn] client = yes accept = 1337 connect = *****.ddns.net:993 cert = /path/to/stunnel.pem

and on server: chroot = /var/lib/stunnel4 pid = /stunnel.pid output = /stunnel.log setuid = stunnel4 setgid = stunnel4 socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [openvpn] client = no accept = 993 connect = 127.0.0.1:1194 cert = /etc/stunnel/stunnel.pem

Example stunnel.log is in attachment. Thank you very much
