# Known workarounds

## No Reuseport

Try running with `LIBP2P_TCP_REUSEPORT=false ./ipfs daemon` and see if that is still happening.

## No TCP

Try running with thoses config:
- `ipfs config --json Swarm.Transports.Network.TCP false`
- `ipfs config --json Swarm.Transports.Network.Websocket false`
- `ipfs shutdown` ***restart your node for the new config to take effect***
