1. Manual ssh node date all successfully indicates that there is no problem in mutual trust
2. Check mos document ID 2555697.1 If OpenSSH is upgraded to 8.x, there will be this problem

Workaround on MOS
# ssh -V
OpenSSH_8.0p1, OpenSSL 1.0.2r 26 Feb 2019
# Rename the original scp.
mv /usr/bin/scp /usr/bin/scp.orig

# Create a new file </usr/bin/scp>.
vi /usr/bin/scp

# Add the below line to the new created file </usr/bin/scp>.
/usr/bin/scp.orig -T $*

# Change the file permission.
chmod 555 /usr/bin/scp

Change it back after installation is complete
# mv /usr/bin/scp.orig /usr/bin/scp

My ssh is version 8.0. According to the operation on MOS, it has not been solved. Finally, the ssh and scp of the 7.x version on the server are used to replace the current ssh and scp and it is solved.
