Thanks for clarifying, I didn’t realise some of those environment variables overlapped with the other settings in the file. I have now got ttn-lw-cli working properly after changing all the config variables in the github issue I linked. I’m going over my tts install process again to see which of these extra variables were needed. Once that’s done I’ll post the full process here so that (a) people googling this in the future can find it and (b) the install documentation can be updated as needed.
