Error while waiting for device: Timed out after 300seconds waiting for emulator to come online.
This error message indicates that the emulator is taking too long to start up and connect to the development environment. There are several possible reasons for this, including insufficient resources on the host machine, slow network connectivity, or issues with the emulator image itself.
To resolve this issue, you can try the following steps:
1. Check your system resources: Make sure that your computer has enough RAM and CPU power to run the emulator. Close any unnecessary applications that are running in the background to free up resources.
2. Restart the emulator: Try restarting the emulator and see if it connects to the development environment within the timeout window.
3. Check your network connectivity: Slow or unstable network connectivity can cause the emulator to take longer to start up. Try connecting to a different network or resetting your internet connection.
4. Use a different emulator image: If the issue persists, try using a different emulator image or version to see if that resolves the problem.
5. Increase the timeout value: If none of the above solutions work, you can try increasing the timeout value in the development environment settings to give the emulator more time to start up.
ssh: connect to host port Connection refused
It seems like you are encountering an SSH connection issue with a specific port. There could be a few reasons for this error. Here are a few troubleshooting steps you can try:
1. Verify the SSH service: Make sure that the SSH service is running on the target host. You can check the status of the SSH service using the command `service ssh status` or `systemctl status ssh`.
2. Check the SSH port: Ensure that the SSH server is listening on the correct port. By default, SSH uses port 22. If you have changed the SSH port, make sure to specify it explicitly while connecting using the `-p` option, like `ssh -p <port> user@host`.
3. Firewall settings: Check if any firewall is blocking the SSH connection. If you have a firewall enabled, make sure to allow incoming connections on the SSH port.
4. Network connectivity: Ensure that there is no network connectivity issue between your machine and the target host. Try pinging the host to verify connectivity.
5. SSH configuration: If you have access to the SSH server's configuration file (/etc/ssh/sshd_config), make sure that it allows remote SSH connections and permits your user to connect.
Please note that these steps assume you have proper access rights and credentials to connect to the remote host. If you continue to face issues, it might be helpful to provide more details about your setup and any specific error messages you receive.
