Unable to install duckdns addon after fresh RPi4 install

Nevermind. I was triple-clicking to highlight the duckdns token, and it was selecting the spaces before the token as well. I didn’t realize because it’s hidden when I pasted it.

I was basically entering an incorrect token. I’ve straightened it out.

Found your post as I was having the exact same problem. Apparently I also had a space before my token. I was pulling my hair out for the last hour, but thanks for saving me.
