Facing the same issue following the CLI version of https://github.com/Chia-Network/chia-blockchain/wiki/Farming-on-many-machines.
I run all services on the main server and only the harvester on the remote nodes. After the whole chia init -c tmp/ca thing, it has imported all the CA files. After start the harvester I get the error described here.

Nevermind, I had a chia node running. I had to stop all chia* processes and then it worked.

If you are still experiencing the issues it is recommended to upgrade to the latest version of chia. Please download it from here: https://www.chia.net/downloads/

Since this issue has been open for a number of years without additional comments, we will be closing this ticket but if we have closed this ticket in error do not hesitate to reach out to us again with any followup questions, comments, or if the issue persists after an update.

Please note that upgrading major versions of chia generally requires the config.yaml to be recreated using these steps:
1. Stop chia
2. Rename the config or move it to a different directory
3. In CLI run chia init
4. Copy any custom settings from the old config to the new (plot drive directories, pool info, trusted node info, etc) - be careful here as yaml is very picky about formatting including those leading spaces
5. Start Chia

The best place to reach our support team is on Discord (https://discord.gg/chia) or by reopening this ticket.
