Issue
You've deployed Dynatrace to your infrastructure and you expect to see RUM data coming in but you cannot see anything being captured in Dynatrace, when you open the developer tools you notice that there is a 403 status for the JavaScript Agent or the Beacon requests (which hold RUM data that will be sent back to Dynatrace).
- JavaScript Agent 403 example:
- Beacon requests 403 example:
What is this error and why is this happening
Definition of 'HTTP 403': HTTP '403 Forbidden' client error response status code indicates that the server understood the request but refused to process it.
This error is usually thrown because you have a firewall that is blocking these requests.
Solution
The fix here is straight forward and there are 2 options you can use:
- you will have to unblock these requests. We have a document containing all of the requests and headers that need to be allowed: https://docs.dynatrace.com/docs/shortlink/rum-firewall
- Configure a beacon forwarder (This fix does bypass the infrastructure and sends data directly to the cluster ActiveGate but there is a possibility that the traffic is also blocked): Web -> Application -> Settings -> general settings -> Beacon endpoint -> Cluster ActiveGate
