We have tried to launch the dynatrace webclient 6.5 version after server process has been running successfully. And we have tried with various other machines as well.
Kindly help us to resolve this asap.
The Java Webstart Client requires a JRE >= 1.8.0_45
Try to download the latest JRE from the highlighted link.
Secondly, open the Client > Settings > Dynatrace Server > Certificate Management and check the Overview Tab for the present certificates.
