Post-install checklist

Tick every item before the first paid product. A save that succeeds with an empty catalog is the usual reason Create fails later.

#Modules and access

• modules/addons/SrvProxmoxSuite/ is present
• modules/servers/SrvProxmoxSuite/ is present
• Addon Proxmox Suite is activated and admin roles are granted
• Encoded build: srvprox.lic is in both folders
• Addons → Proxmox Suite → Info accepts the license key
• Nodes → Clusters List opens without a PHP fatal

#Farm connectivity

• At least one cluster is saved under Nodes → Clusters List and Health succeeds
• System cron is installed
• Configuration → Cron Scheduler has been run for Farm catalog cache
• Nodes → Nodes List shows online nodes

#Placement and addressing

• At least one Active policy under Nodes → Policy Manager, with a cluster, a load-balance rule, and IP pools
• An IPv4 block under Resource → Network → IPv4 Addresses (IPv6 or IPv6 Subnets only if you sell them)
• Those pools still have free addresses

#Media and packages

• KVM and/or LXC templates imported, or the ISO library populated
• Optional: OS families, groups, firewall templates, backup templates
• Products → VM Plan → VM Plan: package saved and Active, with a policy selected
• WHMCS product module is Proxmox Suite, with Guest Type and Hardware Package set

#Client experience

• Configuration → Client Area Features reviewed. This page is what VPS clients actually get.
• Console left in direct mode, or the proxy helper is running if you enabled it
• Test order: the guest exists on Proxmox and the service is linked on VM List → VMs List

#Operations

• Operations → Task History shows the test job, and any failed row has been retried or cancelled
• Error Log was checked after the first provision

#Next step

Walk first steps if any box above is still empty.
