Has anyone resolved this error notification at the top of the EOC web console?

I have 2 SolarWinds Server adding to this EOC, one having SAM 6.1.1, NPM 11.5.0 and NTA 4.1 and second with only SAM 6.2.1. The EOC is installed in the same server as the one having SAM, NPM and NTA.
EOC version 1.6.2.
Had checked the KB indicated but it did not help.
Any advise?
Thanks.
