If EpocCam is using Wifi and not connecting to a PC or Mac, the following troubleshooting steps can be used. 

Reinstall EpocCam Driver

Download the latest EpocCam driver for your Computer:

EpocCam Release Notes - Windows

EpocCam Release Notes - macOS

Once downloaded, please proceed with installing the driver for EpocCam again and restart your computer.

Restart the EpocCam service (Windows only)

Restarting the EpocCam service can solve connection issues. 

1) In Windows search, type Task Manager and open Task Manager.

2) At the bottom left of Task Manager click on More details.

3) At the top right, select the Services tab.

4) In the services list, scroll down and find the service named EpocCamService

Note: Pressing E on the keyboard will immediately jump to services with names that start with E.

5) Right click on the EpocCamService and select Restart.

6) After a few moments the service will have restarted.

Check firewall settings

Check your firewall settings. Your firewall application can block the traffic between your PC and phone.

If you use the Windows Firewall, the Windows installer for EpocCam will automatically configure it to allow traffic.

If you are using third party firewall software like Norton or F-Secure, you will need to configure them to allow Bonjour-service traffic on UDP port 5353. 

allow 'KinoniSvc' to accept incoming connections to TCP port 5055.

Restart the PC, Mac, or iOS device

Restarting the device can solve many different issues.  
 

Reset Router

Restarting the router can solve many different issues.  

Each router has a different way it can be reset.  There may be a button on the router, or a local web page you can go to.

If you don't have those options, you may need to unplug and replug the power cable from the router, but you may want to check with your ISP to make sure that's recommended.
 

Connect PC or Mac to Router

For EpocCam to connect to a computer the iPhone/iPad and computer must be connected to the same network. 

This connection can be either Wi-Fi or wired Ethernet connection.

Check advanced network settings

Certain settings on a Wi-Fi router can prohibit devices on the network from communicating with each other. This would result in EpocCam not being able to connect to a PC or Mac on the network. 

Double check that these services are either disabled or enabled, respectively. 

Ensure that these services are enabled on the Wifi router:

• Multicast
• Internet Group Management Protocol (IGMP)
• mDNS

Ensure that these services are disabled on the router, as they could prevent EpocCam from connecting to a PC or Mac on the same network:

• AP/client isolation
• Virtual Private Networks (VPNs)
• Proxy Servers
• IGMP Proxy
