At trust certificate screen - which option you selected ?
Proceed with this Certificate - Yes or No?
Can you please check why the certificates are in different Language ?
Also please use the Web client on the secondary NSX manager and generate the Self signed Certificate again and try this step again . Please Share screenshots with us if it fails .
Have you verified that the Self-Signed certificate is not expired ?
Are you using the same NTP server on all the devices and does all devices have access to that NTP server?
Also did you do a "clean install" of the NSX manager or did you clone it? You should do a clean install...
We have found issue with VMware support, its GUI issue , We have french swiss Windows with English language pack. In logs of NSX manager we have found french word when we try to accept certificates.
For workarround we have use Windows Server with full English language et without langage pack, and it's solve issue.
Thanks all for your help
