- Twingate Component: Client | Resources
The following are possible reasons that you cannot access a Resource you expect to be able to access via Twingate. They are sorted from most to least common based on our experience.
- Verify you are authorized to access the Resource. If the Remote Network is green but clients do not show the Resource in question in the Resource list (in the tray menu) when signed in, it is likely a permissions problem. Make sure that the user is in a Group that contains the Resource. If the client does not show the Resource, it will not be reachable.
- Verify that your device's DNS configuration. If you are attempting to access a Resource using its name, and you have verified that you are authorized to access the Resource in Twingate, then you may be overriding DNS with a local hosts file. If present, remove any entries in your local hosts file that refer to the Resource. Windows users can find this file at
c:\windows\system32\drivers\etc\hostsand macOS/Linux users can find this file at
- Installed incompatible third party software. Endpoint security software, DNS, VPN, or VPN-like software can prevent accessing a Resource. See Known Incompatibilities for further details.
Verify that your device is not blocked from outbound Internet access to our service. For client connections to Twingate to succeed, access must be allowed to
<tenant>is your tenant name, and the full range of Google Cloud Provider external IP addresses, available here. Note that this list is updated by Google from time to time (context here).
Verify that the destination Resource is available. If none of the above steps are successful, it's possible that the destination service is not running or the host is shutdown or offline. Verify the Connectors have access to the destination service. If using a systemd or AWS AMI deployment, SSH to the Connector(s) and test port connectivity with the example test command:
curl -v telnet://<IPorHostname>:<port>
- Regions that can be blocked from access. While Twingate does not explicitly block certain regions or countries, our upstream provider Google Cloud Platform does block some regions or countries.
