We are extremely sorry about the issue. You can try the following steps to fix the current problem.
If the server has server has 1 CPU, then a quick fix is to restart PM2 from cleavr > web app > deployments and then on the app status, click the ellipsis menu item and then click restart app.
A more long-term fix is to update exec_mode to fork as opposed to the cluster. And, also change instances from max to 1 and then redeploy the app so that the new PM2 config settings hit the server.
Feel free to send a message if the issue still exists.
