So I am not using the cloudflared tunnel CLI Auth. Instead I am creating the Tunnel through Cloudflare API Endpoints and then making DNS Changes. I use credentials data from the tunnel creation Endpoint and store it as a JSON File and then reference that for credentials in my config.yml
Your tunnel was deleted at “2022-10-18T17:13:48.994724Z”, which is why you are getting that error.
You can go to the dash.cloudflare.com Audit Logs to search for the “Cloudflare Tunnel Delete” event at that time to see the user in your account who did it.
