Question

When i try to monitor my server with pm2.io, I am getting the error [PM2 I/O] Unexpected error : Missing mandatory field refresh_token to make a POST request on /api/oauth/token

Same thing has happened to me on an RHEL system (it worked fine a few months ago on another, older RHEL system). I haven't figured it out, but this post has a very simple workaround:

Basically, login to pm.io from the browser, click CONNECT, copy the pm link command, and use it instead of pm login.
