Re-enable the web-GUI of a FLEX 500H with ssh terminal

Hi, I should reactivate the web-GUI interface of a Flex 500H
if I try to check the status from ssh terminal with commands

show state vrf main http-server server
show state vrf main http-server secure-server

both result disabled.....

I tried to re-enable them from ssh with commands

edit running
vrf main http-server server / vrf main http-server secure-server
save

but they are always disabled even after the reboot
where am I wrong?

Thank you
