Hi @aaouane80 ,

If you can ping this means that you have DNS working and network connectivity - the most common issues causing such error.


By the way the correct command to update Firmware/Software list of availalbe versions is

> request system software check
# After that you can see the list
> request system software info


The ping is confirming network connectivity, but fetching updates could still be blocked if you have any firewall on the path. Is there any firewalls on the path between FW and internet? Any restrictions or SSL decryption applied for this traffic?


Note also that your firewall needs to have correct time set in order to correctly validate update server certificate.
