After Upgrading R81 LDAPS communiction stops working

[Harmesh_Yadav]

Dear Team ,

WE have  MGMT at HO location (VM) which we have recently upgraded from R80.30 to R81

And some branch location Security Gateways also we have upgraded To r81 from R80.30

HUB and Spoke topology - Star VPN is working properly earlier and after R81 some time we are getting disconnection issue .

Also I want to create User based Policy and want add user group in Access role for which i am getting error .

 I am enabling LDAPS and trying to fetch certificate but getting error

"Faild to connect to LDAP server connection failed

Traffic we can see from MGMT to Server till Branch Gateway after we are not getting traffic and in log -VPN encryption showing decryption not showing

Please give us idea if anyone have same issue .

Regards,

Harmesh Yadav
