Frequently asked questions (FAQ)
No available allocations – what does it mean?
All ports in the node range are taken. In Admin → Nodes → Allocations add new ports or free unused ones.
Port already allocated / in use?
Duplicate allocation on node. Delete old server or pick another port. ss -tlnp shows used ports.
Server won't start due to allocation?
Check primary allocation (Server → Settings → Allocation). Port must exist on node and be free.
