# Troubleshooting

## Polygon network connection error

Polygon, like all networks to which we can connect our wallet, has specific connection settings that are usually passed on automatically. 

However, it can happen, especially after a long period of inactivity, that these settings have changed over time and the settings provided to our wallet are not up to date. 

This type of problem can lead to a connection error that prevents us from accessing our management interface.

We can solve this problem in a few simple steps:

Open the Metamask extension and select the drop-down menu in the top left corner that lists the networks you have added to your wallet. Since you cannot operate on the currently active network, switch to another network. The default Ethereum network will work fine for this purpose.

So do the switch. Now you can delete the old connection to Polygon by clicking on the little red trash can icon next to the network in the list.

Delete the old connection.

Still in the list menu, click '**Add Network**' again.

Repeat the operations already seen [here](/coderblock-lands/landowner-onboarding/associate-your-lands-to-your-wallet/switch-to-polygon.md).

The network has been added to the wallet again with all the updated specifications: you can proceed with the switch and return to Coderblock Studio.

## 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-en.coderblock.com/coderblock-lands/landowner-onboarding/manage-your-lands-in-coderblock-studio/troubleshooting.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.
