Cant access AWS RDS after pritunl upgrade

Pritunl

HI all,
we upgraded pritunl version to 20 and trying to access AWS services, we were able to access most of the services but couldnt access rds with the endpoint but can access with private IP.
we dint change anything apart from the pritunl version
all the servers and routes are pretty much same with what we had with old version of pritunl

Please advise what could be missing here, we are using enterprise subscription and enabled DNS routing

For AWS DNS routing should be disabled and VPN client DNS mapping should be enabled. This will route the DNS queries through the Pritunl server.
