SDWAN Manager 20.15.3: startup fails

[dbillon]

Hi,

I try to deploy Cisco SDWAN Manager 20.15.3 on Azure.

After the initial setup (data disk format and next steps) the Manager reboots but it does not start properly.

I keep getting the following error in /var/log/nms/vmanage-server.log:

06-Jul-2025 17:54:28,763 UTC INFO  [] [vmanage] [ApplicationDepensChecker] (vManage-akka.actor.default-dispatcher-4) || Error while checking container component (configuration-db) on server (169.254.1.5), error: Connection refused (Connection refused)

Any idea ?

BR, Damien.

My bad .. the instance type chosen by my automation script was not compatible with this release.

Ensure Adequate Resources

Azure VMs running vManage should meet Cisco's minimum requirements:

• Memory: At least 16 GB RAM (preferably 20 GB or more)

• vCPUs: Minimum 8 cores, but 16 vCPUs is recommended for smooth operations

From community posts, insufficient resources often cause the Neo4j database to fail starting, resulting in “Connection refused” seen in vmanage-server.log.
