Access localhost from another computer

Localhost, as the name suggests, points at the localhost. Use the hostname or IP from your computer on their PC's. ie something in the 192.168.x.x or 10.0.0.x range most likely.

 

This site can’t be reached - localhost refused to connect.

I'm trying to connect to my Cyber Power UPS web based management software (PPBE) but keep receiving:

This site can’t be reached localhost refused to connect.

Search Google for localhost 3052 agent

ERR_CONNECTION_REFUSED

I get the same error in Chrome, Edge and Firefox. I can't think of anything that's changed on my network to cause this. Can anyone help? It seems like a port issue but I haven't found a definitive solution.

 

Failed to connect to localhost

Hi Mike,

One of the possible reasons why you were unable to connect to the localhost
is because of the configuration set within the LAN (Local Area Network). To better assist you, we need the answers to the following questions:

• Are you using a computer connected to a secured network or
  domain?
• Have you tried resetting your router to default?

In the meantime, we suggest running the Network troubleshooter
to find and fix issues with your internet connection. To do this, please follow the steps below:

• In the search box on the taskbar, type Network troubleshooter, and then select Identify and repair network problems from the list of results.
• Follow the steps in the troubleshooter and see if that fixes the problem.

If that doesn’t fix your connection problem, try these things:

• Reset the TCP/IP stack
• Release the IP address
• Renew the IP address
• Flush and reset the DNS client resolver cache

To run these networking commands in a command prompt window

• In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator > Yes.
• At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:
  • Type netsh winsock reset and press Enter.
  • Type netsh int ip reset and press Enter.
  • Type ipconfig /release and press Enter.
  • Type ipconfig /renew and press Enter.
  • Type ipconfig /flushdns and press Enter.

We are looking forward to your response.
