- Serious Bug in NSX version 6.2.2 leads to intermediate disconnection of the Guest VMs.
- The issue identified is due to the reason that NSX controller shows disconnected in the Web Client.
- This leads to data path issues for VNIs handled by the disconnected controller.
- VMware published the below KB article, explanining that the issue is due to the IPSec Re-keying feature which is disabled by default in the version 6.2.2
Recommendation is to disable the IPSec communication between the NSX controller or upgrade to version 6.2.4
I recommend to disable the IPSec rather than upgrading to the 6.2.4 version.
