SCP connection closed

[rabby]

Hello everyone,
Since last two weeks i am facing a new issue in SSH. whenever i am trying to add some more files on my VPS using SCP then it says connection closed. I tried almost everything like reinstalling SSH, enabling and disabling. But nothing works. In fresh install of Hestia it works only within 1st 10 min and after that it stop working.

But, can you connect using ssh?

Show the output of these commands?

grep -Ev '^#|^$' /etc/ssh/sshd_config
iptables -S
ls -lR /srv/

Out is so long. Please be specific what i need to look. Because everything else is working on my server except SCP.

If SSH is working SCP should work too, maybe you mean SFTP?

@rabby

Out is so long.

grep -Ev '^#|^$' /etc/ssh/sshd_config
iptables -S
ls -la /srv/ftp/
ls -la /srv/jail/

I’ve never actually read a complete guide on how to manage Linux. I’ve gone through tons of articles, specific how-tos for certain services, and lots of forum posts, but I’ve never used a guide that tries to cover everything. So I’m afraid I can’t really recommend one.
