I have allowed the endpoint Dynatrace end point url however I am still getting error.

Hi,
In logs I see this: context deadline exceeded (Client.Timeout ... while reading body)
So the bootstrapper/initContainer starts downloading but can’t finish in time, almost always egress/proxy/TLS/DNS/firewall.

Dynatrace Operator provides the right knobs in DynaKube:

• .spec.proxy – proxy settings for Operator/ActiveGate/OneAgents
• .spec.trustedCAs – custom Root CAs (mandatory with corporate TLS inspection)
• (temporary test) .spec.skipCertCheck

DynaKube parameters for Dynatrace Operator 
Please verify from inside the cluster/namespace (same as the injected application pods) whether you can download via the Dynatrace API endpoint. For example, run a temporary curl pod and test:

• a small API call 
• the installer download endpoint 

If the installer download fails / hangs / times out from the cluster, then the issue is confirmed as network/proxy/TLS/DNS and needs to be fixed there (proxy + trusted CA + egress rules).

If the installer download works from the same namespace, then networking is likely OK and we should continue troubleshooting elsewhere
