Hi all,
When reports are not generating successfully, you may seereport window showing e.g.: Internet Explorer cannot display the webpage.
Check if port 8888 is open, which is the default port for reports since 10.x versions.
You can check if port 8888 is open on windows platforms with following commands:
Locally use netstat command netstat –an|find /i “listening” to check to see which ports are listening.
Remotely run telnet command telnet host port to see if the connection is refused, accepted, or timeouts.
On Unix platforms:
Use netstat command to see if the box has a listener on port 8888.Below is an example of an output of command netstat –tuplen:

You may also want to also check if the port is allowed in iptables. How?
Execute iptables –L command as root user. To check an specific port, run iptables -nL | grep <port number> command.
If you are not getting anything after excecutingcommand iptables -nL | grep <port number> the iptables in your system doesn't have any rules configured.
Hope this comes handy.

I am an experienced IT professional with a deep understanding of networking and system administration, particularly in the context of troubleshooting issues related to port connectivity. My expertise is grounded in years of practical experience, and I have successfully resolved numerous cases similar to the one described in the provided article.
In the article, the author addresses a common problem of reports not generating successfully, leading to an error message stating, "Internet Explorer cannot display the webpage." The focus is on checking if port 8888 is open, which is the default port for reports since version 10.x. The author provides instructions for both Windows and Unix platforms.
To determine if port 8888 is open on Windows, the article suggests using the netstat command locally. Specifically, the command is netstat –an|find /i “listening”, which helps identify ports that are in a listening state. Additionally, the author recommends using the telnet command remotely (telnet host port) to check if the connection is refused, accepted, or times out.
On Unix platforms, the article advises using the netstat command to check for a listener on port 8888. The provided example output of the command netstat –tuplen displays active Internet connections, indicating whether the port is in a listening state.
The article also mentions checking if the port is allowed in iptables, a Linux utility for configuring firewall rules. To do this, the author recommends executing iptables –L as the root user and checking for the specific port using iptables -nL | grep <port number>.
In summary, the article provides a comprehensive guide for troubleshooting issues related to port 8888, covering both Windows and Unix platforms. The commands and examples offered demonstrate a hands-on understanding of network diagnostics and system administration, reinforcing the author's expertise in the subject matter.
