# Troubleshoot community nodes in Duaer

When a Duaer community node will not install or run, check the version, permissions, and node docs, then the instance logs.
## Check these first

Confirm the node version matches this Duaer version, that credential fields follow that node’s docs, and that the instance allows community packages.

If it still fails, read the execution error and the instance logs. Do not treat a community-node failure as a generic core-node outage.
## Questions

### What should you check first when a Duaer community node will not install?

Check whether Duaer allows community packages, whether the node version matches, and whether credentials follow that node’s requirements. Then read the execution error and the logs.
