Hi all,
I have install the syslog-ng v.3.8 on CentOS 7 and using selfsignature (SSL/TLS). I have done the same procedure but using syslog-ng v.3.7 on CentOS 6 and everything works perfect.
Here i have some problems after i done everything and configuration i have the following errors about SSL. Can someone give me some hints ?
