configure ngrok as service > permission denied

Question

I have a permissions error while attempting to setup ngrok as a service.

$ sudo ngrok service install --config /home/m/snap/ngrok/79/.config/ngrok/ngrok.yml


INFO[08-12|19:11:50] open config file                         path=/home/m/snap/ngrok/79/.config/ngrok/ngrok.yml err="open /home/m/snap/ngrok/79/.config/ngrok/ngrok.yml: permission denied"
INFO[08-12|19:11:50] detect init system                       sys=linux-systemd

Installed ngrok on Ubuntu 20.04.4 LTS using snap.

sudo snap install ngrok

which ngrok
/snap/bin/ngrok

ngrok config check
Valid configuration file at /home/m/snap/ngrok/79/.config/ngrok/ngrok.yml

current permissions.

I had the same problem with Ubuntu 20 / ngrok installed via snap. Like you I couldn't figure out what happens with permissions. Solved it by reinstalling ngrok via apt (see https://ngrok.com/download).
