# Network Connection Issues

Luffa has distributed nodes around the world, allowing anyone to engage in encrypted communication with Luffa users from any country. If you are unable to connect to Luffa, or unable to send or receive messages, please check to ensure you are connected to the network.

The specific steps for the mobile version are as follows:

1. Open the conversation. Is there a clock icon next to the message instead of a check mark? If you see the clock icon, this means your message has not been delivered.
2. Check if the network signal on your device is flickering or absent.
3. Open a webpage in your device's browser to see if it loads. If it does, this indicates that your device is connected to the internet.
4. Check if you can connect to other applications.

If you are able to connect to other applications but cannot connect to Luffa, go to the Luffa conversation list, click on the node icon, enter the node page, and switch nodes. Alternatively, restart the app to see if the connection can be reestablished.

If the issue persists, please contact your mobile operator. They may be able to assist you with adjusting settings to ensure Luffa operates normally.

The specific steps for the PC version are as follows: If you are unable to connect to Luffa, or unable to send or receive messages, please check to ensure you are connected to the network.

If you are connected to the network but still unable to send or receive messages, try the following:

1. Exit the Luffa desktop application and restart it.
2. Log out of the Luffa desktop application and then log back in.
