As stated above i am unable to connect my homebridge into the home app. The iphone is connected via wifi and the raspberry pi is connected via ethernet but these are the same wifi network. I am using the smarthings plugin from here https://github.com/tonesto7/homebridge-smartthings-tonesto7 but I dont think that is what is causing the issue. I believe this is an issue with the HAP server authentication but not sure what. The same error occurs with a sample config as well.

@evy0311 if possible, can you try update node to some recent version? Like 10.x or 12.x?

Uninstall homebridge and plugins and install them again
