Just replace the old domain with the new domain - the rest should remain the same. So change https://1.1.1.1/whatever to https://2.2.2.2/whatever (where “whatever” is the rest of the URL). Edit: I tried this and it works.
The Quick URL does have a pass word (not pass phrase), though.
Hopefully it’s one of your favorite easy to remember passwords, so you may still be able to get in.
