Hi Team,

We are using Percona server for MongoDB version 4.4  
We have a 3 node replica set where in Database Profiling is enabled.  
PMM-Server Installed on Amazon EC2 Instance using Docker.  
pmm2 client version - 2.29.1

Using the below command to add mongodb service.  
pmm-admin add mongodb --username=user\_name --password=password --environment=DEV --query-source=profiler

When we browse the PMM-QAN page, receiving error message saying “Unknown Error”. (Please refer to the below screenshot for reference).

When checked the qan-api logs, saw this  
Log level: info.  
stdlog: Connection: dial tcp 127.0.0.1:9000: connect: connection refused  
stdlog: qan-api2 v2.20.0.

Please review and help me out.

Thank you,  
Kiran

Hi Team,

We were able to figure out the Issue here.  
PMM-Server version we are on is 2.20.0  
pmm2-client version is 2.29.1

We tried upgrading the pmm-server version to 2.28 and It resolved the connectivity Issues.

Thank you.
