cat through ssh does not work, it hangs on "debug2: exec request accepted on channel 0" and scp never finishes

Question

I trying to print a file through ssh on CentOS7 but it does not work somehow :

$ time timeout 60s ssh -vvv SERVER-01 cat /etc/yum.repos.d/CentOS-Base.repo

However, it works fine with another file (with the same access rights, it's weird) :

$ ssh SERVER-01 cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

export PATH

I also cannot scp .bash_aliases (small file) to SERVER-01, it never finishes :

$ time scp -vvv -p .bash_aliases SERVER-01:

On the SSH server side, the file created is empty :

SERVER-01 $ ls -l .bash_aliases
-rw-r--r-- 1 root root 0 Jan 16 11:23 .bash_aliases

EDIT0 : The commands ls -l and md5sums work fine :

$ ssh SERVER-01 ls -l /etc/yum.repos.d/CentOS-Base.repo
-rw-r--r-- 1 root root 1760 Jan 16 12:23 /etc/yum.repos.d/CentOS-Base.repo
$ ssh SERVER-01 md5sum /etc/yum.repos.d/CentOS-Base.repo
ea25f14f85de10190ac0127b15dbe457  /etc/yum.repos.d/CentOS-Base.repo

Here is the line that appears on the sshd server side

SERVER-01 $ journaltcl -f -u sshd
Jan 16 14:26:24 SERVER-01 sshd[7075]: Accepted publickey for root from 172.16.X.Y port 45852 ssh2: RSA SHA256:XYZTV+HIDDENXXXXXXXXXXXXX+xyZ

EDIT1 : It works on another clients. It was another MTU mismatch problem on one switch between the source and the destination. Problem solved.

How can I solve this ?
