Hi,

Were you able to download ActiveGate shell script from tenant? It is important you are using latest shell script version and it is executed with root privileges.

Best regards

Yes, I have downloaded the ActiveGate from the tenant. Just facing issue while installing.

Hello guys,

So this usually points to a network/proxy/TLS issue on the ActiveGate host, not the Dynatrace environment itself, especially since it happens in multiple environments.

[MaximilianoML · Accepted solution]

That means the server starts downloading the capability, but the HTTPS connection gets interrupted.

I’d suggest checking these first on the Ubuntu server:

• Outbound access to Dynatrace on port 443
  Make sure the server can reach the exact Dynatrace endpoints shown in the ActiveGate install page.
• Proxy / SSL inspection
  If your network uses a proxy or TLS inspection, ActiveGate may need explicit proxy configuration and the proxy/root CA imported.
• Clean reinstall
  Uninstall ActiveGate, clear the package/cache folders, then reinstall.
• Logs
  Check /var/log/dynatrace/gateway/ (or somewhere, not sure) for handshake, certificate, proxy, or connection reset errors.

Since it fails with RemotePluginModule download, I would focus on firewall/proxy/certificate trust first.

[anuj]

Checked below:

• Outbound access to Dynatrace on port 443:

network is OK

• proxy / SSL inspection check

env | grep -i proxy

Got nothing.

• Checked SSL / certificate issues

Verify return code: 0 (ok)

• Clean reinstall of ActiveGate

sudo /opt/dynatrace/gateway/uninstall.sh

sudo rm -rf /opt/dynatrace/gateway
sudo rm -rf /var/lib/dynatrace/gateway

Reinstalled. But still:

You should also have ownloaded capability packages in /var/lib/dynatrace/packages and the Remote Plugin Module runtime/cache in /var/lib/dynatrace/remotepluginmodule, so removing only /opt/dynatrace/gateway and /var/lib/dynatrace/gateway can still leave stale capability artifacts behind.

Maybe try to remove them first, and we also expects meaningful free space in those areas: the packages directory is sized for 500 MB, the remote plugin runtime area for 2 GB, and the temp area for 4 GB.

I waited for the module to download. Now is Working.

Thanks for the help. 🙂
