Running Debian Jessie + ISPCFG3 (perfect server howto) I followed this tutorial https://www.howtoforge.com/securing...h-a-free-class1-ssl-certificate-from-startssl to add a HTTPS certificate to my ISPCFG3 panel and for pure-ftp. postifx, dovecote, etc. After doing this, my browser now says: Is this something I need to worry about and how can I "fix" this?
Apart from above problem, I tried accessing my emails i.e. via POP3 and found it is warning me about tested via: Code: openssl s_client -connect alfred.ict-consult.co.za:995 the chain looks like this so where is there a self signed one? I only used what StartTLS provided me !? I am confused now :-( Code: Certificate chain 0 s:/C=DE/CN=alfred.ict-consult.co.za/[email protected] i:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Class 1 Primary Intermediate Server CA 1 s:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Class 1 Primary Intermediate Server CA i:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority 2 s:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority i:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority
