the bot works fine for a few minutes and then going offline reload doesnt help

Check your server console errors. It will probably tell you what's going on. 

every 180s the heartbeat timed out then the bot starts up regular goes online for a few seconds and going offline again 

Do you know what Discord Extension version you're using? 

There was an update to the Discord Extension 5 days ago let's see if updating that helps at all. 

where can i see this

On the plugin page you will see near the top is says depends on Discord. Click on that and it will take you to its page.

If you go in Discord Core and set this to true "Enable Discord Extension Debugging" and then reload the plugin it will tell you what's going on.

I think I know what's going on. Can you add me on Discord MJSU#0814. I have a test version of the Discord Extension for you to try.
