私は最近、新しいノートブック（Lenovo Thinkpad E495）にFedora 30をインストールしました。
私の問題は、SSHを介してサーバーに接続しようとしたときにパスワードを求めるメッセージが表示されることです。パスワードを入力しましたが、ssh20分後にログアウトメッセージが表示されると、画面が停止し、何も表示されません。
これはFedoraでのみ発生します。 Ubuntu 19.04をインストールしましたが、完全に機能しました。他のネットワーク（他のパブリックIP）でも作業を試みましたが、私のネットワーク、他のディストリビューション、またはコンピュータでは問題なく動作しました。

# This is the ssh client system-wide configuration file. See

# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.

# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
