Hi,

We are trying to use DNS load balance in a stunnel client with round-robin algorithm.  service.example.com is mapping to two ips. But when we update DNS to remove one of ips for   service.example.com stunnel client still forward requests to both ips. How to make stunnel client to resolve domain name and refresh its cache? 

Here is stunnel configuration.

sslVersion=TLSv1.2
cert = /etc/stunnel/stunnel.pem
output=/var/log/stunnel.log

[service-client]
client = yes
accept = localhost:4680
connect = service.example.com:4680

[service-server]
client = no
accept = 10.10.0.16:4680
connect = loclhost:80

Here is the resolving result for service.example.com.

;; ANSWER SECTION:
service.example.com.        5       IN      A       10.10.0.16
service.example.com.        5       IN      A       10.10.0.8
