Hi Gurus,

Can someone clarify my question about 8443 port opening for SSL config.

Currently I can't telnet 8443 port, But firewall team says port is not blocked.

Can someone cofirm is telnet function is right process to test if port(8443) is open or not?

Firewall team says, there could be some issue with Application :(.

Below is the error.

Can assume when telnet works without any issue, the below issue disappears or vice versa?

this is basic networking knowledge not specific to any product.
1. You check open/used ports with netstat command

2. telnet will not connect to port 8443 if that port is used as HTTPS/SSL port by the webapp server.

3. I'm guessing the error you presented is from tomcat log. Sounds like you have not configured SSL protocol correctly in it.

The issue is fixed.

Before fix :

1. When I do netstat -na --> could not see 8443 & 443

2.Telnet was not working

After Fix :

Resolution : There was an issue with SSL certificate.Once the certificate was re-issued then the issue fixed.

2. telnet started working once the issue is fixed. 8443/443 , one of port would work based on the port used in server.xml.

Thank you.
