When you connect to the server housing Confluence you see the following in the catalina.out
It is best to try to connect to the machine using it's IP

Run "netstat -an | grep LISTEN" command on the Confluence Server. There appears to be nothing Listening on port 80 or 8090
Run "wget http://localhost:8090" see that we are returned the same 500 error we see in the catalina.out
Run sudo iptables -L. Note that there are redirect rules in place.
原因
IP table redirects have ceased functioning as expected
ソリューション
- Disable IP tables redirects with the following Command
- iptables -F
Recreate your IP Tables following our document on how to perform this operation
