大家好，我最近刚完成Ubuntu Server 24.04的全新安装，现在在家庭局域网里用笔记本通过SSH连接服务器完全没问题，但当我尝试用SCP把本地文件传到服务器时，一直收到「connection refused lost connection」的错误提示。我把更详细的verbose调试输出贴在下面，有没有大佬能帮忙分析下问题所在，给点修复建议？

我执行的SCP命令：

scp -vvvv /home/username/Downloads/Anaconda3-2024.02-1-Linux-x86_64.sh username@xxx.xxx.xx.xxx:~/stuff/username_storage/installs/

对应的输出信息：

Executing: program /usr/bin/ssh host xxx.xxx.xx.xxx, user username, command scp -v -t ~/stuff/username_storage/installs/
