+## Server Address Mismatch
+
+If you [configure {{% tts %}} CLI]({{< ref "/the-things-stack/interact/cli/configuring-cli" >}}) to use one cluster server address (for example `eu1`) and try to perform actions on the entities registered in other cluster (for example `au1`), you will probably face the following error:

+error:cmd/ttn-lw-cli/commands:end_device_server_address_mismatch (Network/Application/Join Server address mismatch)
+```
+
+If you want to perform operations on the entities registered in `a certain` cluster, then you need to ensure the CLI `is configured with server addresses for that` cluster.
