If you encounter network issue such as slowness or non responsive when attempt to connect to your APC service, you will need to provide us the ping, trace route and your IP address.

Ping is a basic Internet program that allows a user to verify that a particular IP address exists and can accept requests.

Traceroute is a command which can show you the path the information takes from your computer to one you specify. It will list all the router it passes through until it reaches its destination, or fails to and is discarded. In addition it will tell you how long each 'hop' from router to router takes.

If you are not sure on how to do ping or traceroute, please use the guide below:

This guide assume you are using Windows.

For source IP, please visit https://www.whatismyipaddress.com from the location (such as office, home) you encountering the issue and you will see your IP shown on the site.

Telnet is generally used for checking connectivity from your location to your APC’s server destination ports.  For example to check if the network you are using allows you to connect to a certain port at your server.

How to perform a telnet test from your location:

(Windows PC)
- Click “Start menu” go to “Run” 
- In the “Run” box, type “CMD” 
- With the command prompt open type: telnet <your APC server ip address> <port number>

- Example telnet 8.8.8.8 53



- If successful.


- If not successful you will see error "Connecting To <your APC server ip address>...Could not open connection to the host, on port <your port number>: Connect failed



- There are a number of reasons for the failure and we advice contacting us at support@apc.sg including providing screenshots of your telnet results above for APC to advice further.
