I am trying to get push notifications working for a PWA app and have followed the steps shown here: Push Notifications | Mendix Documentation I am at the part where I would click on the "Register for Push Notifications" button but receive the below error and not sure why. Can someone help me understand where the issue lies? An error occured while registering for Push Notifications: Registration failed - could not connect to push server Nanoflow stack: "Call JavaScript Action: PushNotifications.RegisterForPushNotificationsWeb" in nanoflow "PushNotifications.SUB_RegisterForPushNotificationsWeb" "Call nanoflow: PushNotifications.SUB_RegisterForPushNotificationsWeb" in nanoflow "PushNotifications.ACT_RegisterForPushNotificationsWeb"
