  • Inability to access a local server using the WAN IP/Domains + Port from within the LAN, although it works fine via the LAN IP.
  • Accessing the server via the WAN IP/Domains from an external network works fine.

You uploaded from main unit to update satellite unit? Same issue I'm facing. Because deco blocked your update process as a theat. Delete your device IP from blocked list or update via cable.

@SayeemAhmed 

You can find the IP address of the satellite X50 on the Deco App. Did it help if you tried to log into the individual web UI of the satellite X50 to update it first, then go back to the main Deco X50?

Best regards.

When will the official version of this firmware be released for the X50? Does this version fix the internet upload and download speed limit error?
