If your Live Tail page shows an error, or the logs do not load, try the following troubleshooting steps:
Open the Live tail view with your browser in Incognito mode, and see if you can view logs.
Try a different browser, and check if Live Tail loads logs.
Check whether other team members can see logs in the Live Tail view.
Check for any network restrictions, VPN configurations, or antivirus software that may block the Live Tail from loading logs:
Ensure that your local or company network allows inbound traffic from live.logs.datadoghq.com.
Find the Datadog IP prefixes at the IP ranges endpoint.
Trace requests
Traceroute is a tool that helps you test the path a packet takes from source to destination. You can use traceroute to identify any client-side network issues that may stop Live Tail from loading.
To examine the route for Live Tail logs on Linux or MacOS, run the following command:
traceroute live.logs.datadoghq.com
If at any point the request times out, that means the request is blocked somewhere between the client and Datadog servers. Check with your network administration team to address this issue.
If a step in the route shows * * *, this could indicate a host did not reply to the traceroute, or a router does not reply to that protocol. The * * * pattern does not always indicate a timeout. Changing the discovery protocol to ICMP/PING using the -I option may provide more detailed results.
Clear browser and DNS caches
Browser cache
Clearing your browser cache may help with Live Tail problems. For example, to clear your cache in Google Chrome, see Google account help.
DNS cache
Clearing your DNS cache may help with Live Tail problems.
To clear your DNS cache using Google Chrome:
Launch the Google Chrome browser.
Type chrome://net-internals/#dns in the address bar, then click Enter.
Click Clear host cache.
Check browser plugins and extensions
Browser plugins and extensions, including ad blockers, sometimes interfere with Live Tail:
Check if your browser or operating system has an ad blocker app installed. Uninstall or disable any ad blockers you find, and then check if you are able to see logs in Live Tail.
Pause, stop, or uninstall any browser plugins and extensions.
Determine whether an administrator configured a logs restriction query (RBAC) on your Datadog organization. If you lack the necessary permissions to access the logs you are querying in Live Tail, no logs are visible to you. If you believe you should have access to these logs, contact your Datadog account administrator to grant the required permissions.
