Your Monero GUI wallet is not connecting to the daemon, which is necessary for syncing with the Monero network. When your wallet is not connected to the daemon, you won't be able to send or receive funds until it's fixed. Here's what you can do to troubleshoot and fix the problem:

1. Check your internet connection: Make sure you have a stable internet connection. The daemon requires a connection to sync with the Monero network.

2. Restart the daemon: In the Monero GUI wallet, go to the `Settings` tab, click on the `Stop daemon` button, wait for a few seconds, and then click on the `Start daemon` button. This should restart the daemon and attempt to reconnect.

3. Verify the daemon address and port: In the Monero GUI wallet, go to the `Settings` tab and check the `Daemon address` and `Daemon port` fields under the `Node` section. The default settings for Simple mode should be `localhost` for the address and `18081` for the port. If you have made any changes, reverting to the default settings might resolve the issue.

4. Check the status of the Monero network: Sometimes, the Monero network might be experiencing issues, which can affect your wallet's connection to the daemon. You can check the network status on websites like [xmrchain.net](https://xmrchain.net/) or [moneroblocks.info](https://moneroblocks.info/).

5. Switch to a remote node: If the issue persists, you can try using a remote node to connect to the Monero network. To do this, go to the `Settings` tab in the Monero GUI wallet, change the `Wallet mode` to `Advanced mode`, and fill in the `Daemon address` and `Daemon port` fields with the address and port of a remote node. You can find a list of remote nodes at [moneroworld.com](https://moneroworld.com/#nodes).

6. Check for updates: Make sure you have the latest version of the Monero GUI wallet installed. Updates include bug fixes and performance improvements that might resolve connection issues. You can download the latest version from the [official Monero website](https://www.getmonero.org/downloads/).

If you follow these steps and still encounter issues, you might want to seek help from the Monero community on forums like [Reddit](https://www.reddit.com/r/Monero/) or the [Monero Stack Exchange](https://monero.stackexchange.com/). They can help you more for your specific case.

try changing the remote node in settings and then wait a bit with it running
