The following are the known issues:
| Issue | Troubleshooting |
|---|---|
| When you change the user in the Management UI of the IEM, it is possible that you still see the Edge Devices from the previous user. | Clear the cache of your Internet browser and refresh the IEM. |
| It is possible that the error "Out of memory" occurs in the VM with the issue that the IEM is not accessible anymore. | Reboot the VM. |
| Edge Apps do not run due to app signing implementation. | Use the latest IE App Publisher version and create a new version of the Edge App in the IE App Publisher. Afterwards, upload the new version to the catalog of the IEM and install and run the Edge App. |
| When you take a snapshot of the Industrial Edge Management OS (IEM‑OS) in the VM while the VM is running and you restore the snapshot, you will be signed out from the Industrial Edge Management when you open an app in the "Catalog" menu item in the Management UI. Also, when you restore the snapshot in this case, the time of the VM is not aligned with the current time. | To realign the time of the VM, reboot the VM or restart NTP services. When you take a snapshot of the Industrial Edge Management OS (IEM OS) in the VM while the VM is powered off, this issue will not occur and you do not have to reboot the VM or restart NTP services. |
| Deleting a configuration of the IE Databus and the SIMATIC S7 Connector by clicking the "Delete Configuration" button under the "My Installed Apps" menu item starts a task on the according Edge Device but fails immediately. | - |
| Connecting an Edge Device to the IEM fails and the "Nginx configuration test failed" error message is displayed during activating the Edge Device phase. | Check the DNS server configuration since the error message is DNS server related. The DNS server must be configured properly and reachable for the IEM. |
