Cannot remove ADM object if deletion results in an error
| Issue ID | Status |
|---|---|
| 42520 | Open |
Description
If a system error on the nginx instance prevents a new configuration from being applied, it can result in App Delivery Manager objects going into an error state when deleted. This prevents the object from being removed from an environment. Multiple attempts to delete the object will also fail.
Workaround
To remove the object, the instance groups that the object is referencing (direct if a gateway object; indirectly if a component) must temporarily have the instances removed from the instance group.
Duplicate Certificate and Key published for managed certificates
| Issue ID | Status |
|---|---|
| 42517 | Fixed in App Delivery Manager 4.0.0-EA2 |
Description
When deploying a configuration with a certificate and key handled by NGINX Management Suite to a custom file path, it may deploy a duplicate copy of the certificate and key to the default /etc/nginx/ path. When deleting the certificate and key, it will only delete the certificate and key in the custom path, leaving the duplicate copy.
Workaround
Manually delete the certificate and key from the /etc/nginx/ path.

| Issue ID | Status |
|---|---|

Description
It is possible to update an existing certificate’s serial number to one already in use. This incorrectly changes the cert (matching the serial number) details to a new name.
Workaround

| Issue ID | Status |
|---|---|

Config push failure when Agent and NGINX Plus with the metrics module are deployed in a container
| Issue ID | Status |
|---|---|
| 41868 | Open |
Description
When the NGINX Agent and NGINX Plus are installed in a container, and the metrics module is also installed on that NGINX Plus instance, any config push to an instance group with that instance will fail.
Workaround
The stream module requires stream block to be in the config so when loading the metrics module use the stream block as well.
System Metrics not available without elevated access rights
| Issue ID | Status |
|---|---|
| 40945 | Open |
Description
System metrics, as seen in the Overview page, are not displayed for users with roles without elevated access rights, e.g., a Read-only role with no rights to perform other operations like Create, Update, or Delete.
Workaround
None
Modules that share the same Instance Group can create config conflicts
| Issue ID | Status |
|---|---|
| 38638 | Open |
Description
When multiple modules are deployed on the same NGINX Management Suite instance, modules may configure the same server block, and only one config will be applied.
Workaround
Use Role-based Account Control to prevent sharing of instance groups between App Delivery Manager and API Connectivity Manager.
