Root Cause:

The original debug_scp.c only match suffix with .gpg & sys_debug.tar.gz,

but with the CLI command: show debug file, sys_debug file is along with timestamp, like sys_debug_20260112_051232.tar.gz.

Result in scp only send .gpg
Solution:

Match sys_debug.tar.gz with extra timestamp: sys_debug_20260112_051232.tar.gz

Under array:
show debug file
sslkeylog

sys_debug_20260112_051232
debug scp "root@192.168.97.201:/tmp"    // "" is needed
Under root:
ls -l /tmp/ | grep sys_debug
sys_debug_20260112_051232.tar.gz
