@_elena DNS setup is not actually difficult but it can be hella confusing when you start or if you pick up someone else's config. it is very precise though, so when things don't work: make sure of all the details (typos, case, ...) and then give it some time, and then make sure to use different browsers with all history wiped for testing. https://dnschecker.org and the CLI tool 'drill' are also very useful here
