# Pterodactyl Allocation Error – Port in Use & "No Available Allocations"

Pterodactyl allocation errors: port already in use, no available allocation, server won't start – fix nodes, Wings & port range.

**Quick answer:** Pterodactyl allocation errors: **add new ports on node**, remove duplicate allocations and check server **primary allocation**.

**If you landed here:** "No available allocations", "Port already in use" or server won't start due to port conflict.
