Hi,
I have to create tunnel between server and client. Client have proxy configured in between.
So i use below in /etc/stunnel/stunnel.config. User name and password is correct

pid = /var/run/stunnel.pid
cert = /home/client.crt
key = /home/client.key
options = NO_SSLv2
debug = 7
output = /var/log/stunnel4/stunnel.log
client = yes
CAfile=/home/**chain.pem
verify=2
[test]
protocol = connect
accept = 127.0.0.1:10000
protocolHost = host.vmj.com:443
connect = <PROXYIP>:<PROXY port>
protocolUsername = vmj.com\user1
protocolPassword = VMJTEST!123
protocolAuthentication = NTLM

In stunnel.log, i can see below error
