Fortinet in Q4/24 has remediated this issue in FortiSASE version 24.3.c and hence the customers need not perform any action.
Workarround :
disable the security fabric :
config system csf
set status disable
end
or
remove fabric from config system interface:
config system interface
edit "portX"
set allow access ssh https
next
end
