# Weblogic: Failed Hostname Verification

### Problem <a href="#problem" id="problem"></a>

When using the SeaLights test listener as a javaagent in Weblogic, it fails to load with a 'failed hostname verification check' certificate issue.

{% code overflow="wrap" lineNumbers="true" %}

```
... <Certificate chain received from hostname - xxx.xxx.xxx.xxx --> app.sealights.co failed hostname verification check. Certificate contained *.sealights.co but check expected app.sealights.co>
```

{% endcode %}

### Solution <a href="#solution" id="solution"></a>

As the SeaLights certificate is a general certificate for `*.sealights.co` servers, if Weblogic is set up to perform a hostname verification then this will fail.\
Therefore you should turn off this verification in Weblogic

You can turn off the hostname verification by going to:

* The Administration Console
* Click on **Lock & Edit**
* Expand **Environment** and select **Servers**
* Select the server
* Go to **Configuration**→**SSL**→**Advanced**
* Under **Hostname Verification** select **none**
