# "Failed to get license info" or "Unable to retrieve license info" message with valid license

In some situations, some users are receiving "Failed to get license info" or "Unable to retrieve license info" error messages when using Portainer BE, particularly during the upgrade to BE from CE but this has also been seen during regular use of the Portainer UI.

To resolve this, we recommend clearing your browser's cache and local storage.

**Chrome**

Click on the three dots in the top right of your Chrome window and go to **Settings**, then **Privacy and Security**. Click **Clear browsing data**, change the **Time range** to **All time**, ensure **Cached images and files** is checked and click **Clear data**. You may also need to log back into Portainer after performing this step.

**Firefox**

Click on the three lines in the top right of your Firefox window and go to **Settings**, then **Privacy & Security**. Scroll down to the **Cookies and Site Data** section and click **Clear Data**. Ensure that both options are ticked and click **Clear**. You may also need to log back into Portainer after performing this step.

**Edge**

Click on the three dots in the top right of your Edge window and go to **Settings**, then **Privacy, search, and services**. Scroll down to the **Clear browsing data** section and click **Choose what to clear**. Change the **Time range** to **All time**, ensure **Cached images and files** is checked and click **Clear now**. You may also need to log back into Portainer after performing this step.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.portainer.io/faqs/troubleshooting/logs-errors-and-debugging/failed-to-get-license-info-or-unable-to-retrieve-license-info-message-with-valid-license.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
