Hello All, 

I recently noticed that Vcenter discovery is getting failing for some of the Vcenters and getting. 

Unable to establish connection to https://xx.xx.x.x/sdk: java.lang.NullPointerException: None of url, username can be null. When I test the credentials I am getting Invalid target specified. 

I am using same credentials for all the Vcenters but its not working for only some Vcenters (using external credentials). 

any one faced same issue?

So, you are not trying with the mid server which has been installed at vCenter?

[vamshi19]

yes I am using the mid server which installed at vcenter. same mid servers are working from long time and suddenly stopped working. I just restarted the mid servers than it's started working. 

I think some process struck on the mid server. 

Thanks, 

Vamshi.
