Getting to play with my kid

You can check which servers are open to character creation here: https://na.finalfantasyxiv.com/lodestone/worldstatus/

Coeurl is currently Congested, this means that no characters can be created there. This status is only changed by the devs during patches. The trying at odd hours thing only works for non congested servers experiencing soft locks to character creation due to lots of players being logged in during prime time.

Your son can create a character on a non congested server and you can play with him using the world visit system, or you can wait until Coeurl is no longer set to congested but we have no way of knowing when the devs will change that status.

Edit: Information on world visit in case you aren't familiar with that system: https://na.finalfantasyxiv.com/lodes...de/worldvisit/
