Yes you lose local access, don’t do it, I did and it was a disaster, use the mobile app to login, hopefully you setup that as admin, and change settings back to DHCP and you’ll regain local access, part of the issue is you think it’s address is mycloudex2ultra but it’s not, it’s a foot long device local address with a port number 8543, and after setting static that address is dead until you reset to DHCP through the app.
