I tried using quasar on myself and the target being my vm. it worked. I had my friend in canada download the same exact client, he downloaded and ran it, it was running in the background in his pc, yet nothing appeared on quasar, whats going on

When using Quasar or similar tools, several factors can influence the connection and visibility of the client on the server. Here are some potential reasons why you're not seeing your friend's client in Quasar:

**Network Issues**: Ensure that your friend’s computer is connected to the internet and that there are no firewall or router settings blocking outgoing connections. Quasar clients may need to connect over specific ports.

**Firewall/Antivirus Software**: Both your friend's firewall and antivirus software may be blocking Quasar from establishing a connection. Make sure to add exceptions for Quasar and ensure that it's allowed through the firewall.

**IP and Port Configuration**: Ensure that the IP address and port configuration you’re using in Quasar's configuration settings match those used by your friend’s client. Misconfigured IP addresses or ports can prevent connections.

**Version Compatibility**: Ensure that both you and your friend are using the same version of Quasar. Different versions may have compatibility issues.

**Client Configuration**: Make sure your friend's client was configured correctly and that it's pointing to the correct server IP address and port in the Quasar settings.

**VPN or Proxy Settings**: If either of you is using a VPN or proxy, it may affect the ability to connect. Try disabling these and see if a direct connection is established.

**Client Installation**: Ensure that your friend completed the installation process correctly and that the client is indeed running. Sometimes the client may not start properly or may crash.

**Quasar Server**: Verify that your Quasar server is running and listening for incoming connections. You might also want to check any logs associated with Quasar for error messages or hints as to why the connection might not be established.

**Local Network Issues**: If there are issues with the local network setup or restrictions enforced by ISPs, these could also affect the connection.

If you've checked all these aspects and it still doesn't work, consider reaching out to communities or forums dedicated to Quasar for more specialized support.

Update (2025-11-25):
When using remote access tools like Quasar, there are several factors to consider if one client (like your friend’s) doesn’t appear on your setup. Here are some potential issues to investigate:

**Network Configuration**: Ensure that both computers are on a network that allows communication. Firewalls, routers, or VPNs can block the connection between your device and your friend's VM. Check that the appropriate ports (usually TCP port 443 for Quasar) are open.

**Quasar Version Compatibility**: Confirm that both you and your friend are using the same version of Quasar. Different versions might have compatibility issues or different behaviors.

**Firewall/Antivirus Interference**: Your friend's firewall or antivirus software may be blocking Quasar from making outbound connections. Ensure that Quasar is allowed through the firewall on their system.

**Configuration Settings**: Double-check the configuration settings used for Quasar on both ends. Make sure that the listening IP address on your side matches the server that your friend is trying to connect to.

**Dynamic IP Addresses**: If you are using dynamic IP addresses (common in residential networks), your public IP could change. Ensure that your friend is trying to connect to the correct public IP of your machine.

**No-IP/Dynamic DNS Issue**: If you're using a Dynamic DNS service to track your IP, verify that it's correctly updating with your current IP address. 

**User Permissions**: Check user permissions on both systems. If your friend was running Quasar without the necessary permissions, it may not function as intended.

**Quasar Client Delivery**: Reconfirm that your friend downloaded the Quasar client properly. An incomplete or corrupted download could lead to it not functioning correctly.

**Testing with Another Device**: If possible, have your friend try another device to see if there’s an issue specifically with their original device.

**Logs and Debugging**: Check the logs on both your end and your friend's end for any error messages that might provide insight into why the connection was not successful.

If you've gone through all these steps and the issue persists, it may be beneficial to look through Quasar's documentation or user forums for troubleshooting advice specific to your situation.
