When openning the url the website is unable to load and we are stuck here. We have restart metabase multiple times and it didn't work. Restart the server didn't work neither. Appears that multiple metabase services/processes are running in the backend
Do you host Metabase locally in your own server ? When you run the jar in the console, do you see the output ?
We run Metabase as a service in production
What OS? Can you try disabling the service and try to start the jar manually in the console ? It should display what's going on there.
