Check if your repository db, nodemanager and weblogic are up and running first.
I have checked Repository DB is up and while starting OPMN services from via cmd (command prompt), all components are showing up but still not able to login to EM,console and Analytics. As I have earlier mentioned that NQS server log is throwing the below error:
[nQSError: 12010] Communication error connecting to remote end point: address = 192.168.10.209; port = 80.
[nQSError: 46119] Failed to open HTTP connection to server 192.168.10.209 at port 80.
Any update on this issue?
