Hello Community,

I am performing a Dynatrace Managed cluster upgrade and the upgrade is unable to start.

During the pre-check/reconfigure process, I consistently see errors similar to:

“Cannot connect to Dynatrace Mission Control via network proxy”

The cluster nodes have outbound connectivity configured through a proxy. However, the upgrade and reconfigure operations continue to fail.

What I have checked so far:

- Proxy configuration appears to be configured.
- Upgrade process does not start.
- Reconfigure operation also fails.
- Mission Control connectivity errors are reported in the events/logs.

Has anyone experienced a similar issue during a Managed cluster upgrade?

I was seeing a successful connection using the curl command

But the reconfigure is failing

Definitely look in the logs of the upgrade process (default in `/opt/dynatrace-managed/installer/upgrade`) . Any chance your proxy needs certificate and the one you provided has expired?

Or any chance your proxy blocks some requests to mission control?
