Randomly disconnecting using Textual

[charles-001]

Hello,

I'm using the latest version of Fabric with Textual (a TUI) and am experiencing random disconnections when clicking around in the UI I created. I tested the code below by itself and did not experience any disconnecting, but when using it with Textual is what starts the issue. Any help here would be appreciated as I've tried paramiko by itself and asyncssh without any issue but I'd prefer to use Fabric since my app is already built for it.

Test code:

connection = Connection(host=tab.machine.host_name, connect_timeout=5)
while True:
    command = "echo 'hello'"
    result = connection.run(command)
    tab.logger.info(result.stdout)

    sleep(1)

The error I get is:

ThreadException:
Saw 1 exceptions within threads (OSError):

Thread args: {'kwargs': {'echo': None,
            'input_': <_io.TextIOWrapper name='<stdin>' mode='r' encoding='utf-8'>,
