When you try to connect remotely to another computer, if you can't connect, it could be due to a variety of reasons. Here are some common problems and workarounds:
Make sure both computers are connected to the internet and check if the network connection is stable.
Try restarting your router or adjusting your network settings to resolve possible network connectivity issues.
On the target PC, make sure that Remote Desktop Services is enabled (for Windows, the Remote setting can be found in System Properties).
Make sure that the account you are using has permission to access the computer remotely.
Check the firewall settings of the target computer to make sure that the remote connection software (such as Windows Remote Desktop, TeamViewer, etc.) is not blocked by the firewall.
Temporarily disable your security software or firewall and try to connect again to see if it's the security software.
Make sure that the IP address or computer name of the target computer entered is correct. For dynamic IP addresses, you may need to recheck the current IP of the target computer.
If you use a specific port for remote connection (e.g., Windows Remote Desktop uses port 3389 by default), make sure that the port is open in both the router and the target computer's firewall.
For remote connections that require the internet, you may need to set up a port on your router**.
Make sure that the remote connection software (e.g. TeamViewer, Anydesk, etc.) is properly installed on both computers and is up to date.
Check the settings of the software to make sure there are no configuration errors.
Check that you're using the correct user credentials to connect.
For the enterprise network, check whether you have the appropriate permissions to connect remotely.
Make sure that the remote connection software is compatible with the operating system version on both computers.
When troubleshooting connectivity issues, it's recommended to start with the most basic network connectivity checks and work your way up to rule out possible causes. If the problem persists, consider checking the official support documentation for the remote connection software or contacting technical support.
When setting up a remote connection to your computer, it's important to pay attention to security and avoid revealing sensitive information or credentials.
