Hi,
I updated Electrum and Bitcoin Core to the most recent versions.
Since i updated Electrum and Bitcoin Core my lightning channels are offline. If i check the logs i see that there is an error: i2pd\_daemon\_1 | 09:35:45@905/error - Tunnels: Can’t select next hop for XxH0Hgf587qj6n1vdzt-FvqbQxvOnKFcZIagWJXVRYY=
I disabled Outgoing Connections to I2P Peers but that didn´t fix it.
Here are the logs, hopefully someone can help me:

Hi @ironrock
Sorry to hear that. The I2P error is quite a common log, so I don’t believe it is related to that. Let me forward this to the team.
In the meantime, can you please try the following:
> [@Official Umbrel Troubleshooting Guide and FAQ](https://community.umbrel.com/t/official-umbrel-troubleshooting-guide-and-faq/9873/1):

> To generate more detailed logs for a specific app, follow these steps:
>
> 1. Connect to your Umbrel server by following the instructions in _How to SSH into umbrelOS on Umbrel Home or Rasberry Pi_ or by accessing a terminal on your Linux machine.
> 2. Run the following command (Lightning Node example). If you are on a Linux machine, you may need to replace `~/umbrel` with the path to your installation directory, as described in _Troubleshooting on Linux_:`~/umbrel/scripts/app compose lightning logs --tail 250`You can replace “lightning” with the ID of the app you want to view the logs for. The list of app IDs can be found here: [https://github.com/getumbrel/umbrel-apps](https://github.com/getumbrel/umbrel-apps). Simply use the name of the folder for the app you want to view the logs for.

> To get help understanding the logs and any steps required to solve the issue, copy and paste your logs into [https://0bin.net](https://0bin.net) and then share that link here in the forum, [Umbrel’s Telegram community](https://t.me/getumbrel), or with the Umbrel team using the chat icon 💬 located at the bottom right of [Umbrel.com](https://www.umbrel.com/).

> SSH (Secure Shell) is a way to access and control a device, such as your Umbrel server running on a Umbrel Home or Raspberry Pi, via the command line. To access Umbrel via SSH, follow these steps:
>
> 1. Open a terminal window on your computer. On macOS, you can open the Terminal app that’s installed by default on every Mac. On Windows, you can open Command Prompt or the PowerShell app.
> 2. Type in the following command\* and press the `Enter` key:`ssh -t umbrel@umbrel.local`\*In the command given above, you can replace `umbrel.local` with the local IP of your Umbrel if you prefer. If you are using PowerShell on Windows 10, you may need to run `ssh umbrel@umbrel` instead of the command given above.
> 3. You will then be prompted to enter your password. This is the same password you use to access your Umbrel through a browser. The default password before you have created an account on your Umbrel is `moneyprintergobrrr` on Raspberry Pi, and `umbrel` on Umbrel Home. You will not be able to see your password as you type it into the terminal. Once you have typed in your password, press the `Enter` key.
>
> This will established an SSH connection to your Umbrel server. You can now begin using the command line interface to perform various actions and troubleshoot issues that require SSH.
