Check the firewall to see whether it is enabled.
Also, from the remote computer run the following command to see whether it can listen to your JIRA machine's port 8080.
# telnet xxx.xxx.xxx.xxx 8080
(Replace xxx.xxx.xxx.xxx with your JIRA machine's IP)
Also, try a ping.
- If ping fails, then firewall/ network issues.
- If ping passes and telnet fails, then firewall issues.
- If both pass and still you are unable to access from the web browser, set browser proxy to none (direct connection) and see.
Example of telnet
