Now you are using proxy or you have traffic open wide to Mission Control? We have the same issue as you but with proxy. In our case, self signed certificate was overwrite by proxy to client one. We had to add client certificate (root + cer) to trusted according to this article:

https://www.dynatrace.com/support/help/setup-and-configuration/dynatrace-managed/configuration/how-to-add-a-certificate-to-server-trust-store/

Check in your infrastructure if there is something that can overwrite your certificate and do steps according to link above.

Is there maybe a transparent proxy between mission control and the Dynatrace server?

What is your output of the following command from the Dynatrace server:

echo |openssl s_client -showcerts -connect mcsvc.dynatrace.com:443

Does it show the following?

Server certificate
subject=C = US, ST = Massachusetts, L = Waltham, O = Dynatrace LLC, OU = GTG, CN = mcsvc.dynatrace.com

issuer=C = US, O = DigiCert Inc, CN = DigiCert SHA2 Secure Server CA

That's a symptom of a communication issue to Mission Control. There has to be a transparent proxy in your network - probably firewall - as Julius writes.

Installer checks Mission Control connectivity and downloads license meta information to orchestrate self-monitoring OneAgent.

The error message comes from the JVM - so I assume it's the indirect output of the Server process.

I advise to open a support ticket so our team can make sure your installation works reliably and will help you with proper configuration.
