After update firmware "network or server error, please retry later"

hello

i’ve just updated my note pro.
i have clicked the button to check if a new version of firmware was available, it has been detected and installed.
since, when i check again if a new version exists i have the message “network or server error, please retry later”, so it is not possible to check any new update for the future.

just tell me if you have the same issue or not (i can access internet with the brower though)
thx
