[stunnel-users] stunnel 5.21 - fails to listen on both IPv4/IPv6 (Linux)

[Lonnie Abelbeck]

Very long-time user with the AstLinux project...

stunnel 5.19 works fine, when upgrading to stunnel 5.21 with the same config I get:
--
Starting Stunnel Server Proxy...

Has the syntax changed to listen on both IPv4/IPv6 ?
