Elastic Desktop Service:Network FAQ

Proxy server

A proxy configured on the cloud computer may interfere with internet access. To check, run a remote command that reads the proxy registry key:

1. Log on to the Elastic Desktop Service Enterprise console.

2. In the left-side navigation pane, choose Resources > Cloud Computers.

3. In the top navigation bar, select the target region.

4. On the Cloud Computers page, find the cloud computer and send a remote command in one of the following ways:

   • In the Actions column, click More, then choose Send Remote Commands.

   • Click the cloud computer ID, click the Remote Commands tab, then click Send Remote Commands.

5. In the Send Remote Commands dialog box, enter the following commands and click Execute.

   $ProfileLists=Get-ChildItem -Path "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList" -Name;
   $SidLists=$ProfileLists | Where-Object { $_ -like "S-1-5-21-*" -and $_ -notlike "*-500" };
   Foreach ($Sid IN $SidLists) {
     $a=(Get-ItemProperty -ErrorAction SilentlyContinue -Path "Registry::HKEY_USERS\$Sid\Software\Microsoft\Windows\CurrentVersion\Internet Settings" -Name ProxyEnable).ProxyEnable;
     if ($a -ne 1) {
       Write-output "proxy is off"
     } else {
       Write-output "proxy is on"
     }
   }

If the output shows "proxy is on" and you cannot access certain websites, consider disabling the proxy.

Network interface controller (NIC) status

Check the NIC inside the cloud computer for these issues:

• IPv4 protocol is not enabled on the NIC.

• The NIC is disabled.

• The hop count of the management NIC is greater than the hop count of the user NIC.

To fix NIC issues, use Cloud Computer Manager. For details, see Use Cloud Computer Manager.

Route table

Check the route table inside the cloud computer for these issues:

• The default route 0.0.0.0 is missing.

• The management service routes 100.64.0.0 and 100.100.100.200 are missing.

To fix route table issues, use Cloud Computer Manager. For details, see Use Cloud Computer Manager.

Security software or VPN software

Third-party security software or VPN software installed on the cloud computer may interfere with network connectivity. EDS detects only common security software and VPN software. If such software is installed and you cannot access certain websites, consider disabling the software and try again.

Firewall

The following steps use a Windows OS as an example. The firewall on the cloud computer may block required ports. To disable it:

1. Go to Control Panel > System and Security > Windows Defender Firewall.

2. In the left-side navigation pane, click Turn Windows Defender Firewall on or off.

3. On the Customize Settings page, select Turn off Windows Defender Firewall and click OK.
