Unable to connect to Legion 7.3.5 server

hi, i'm new to WoW Circle, and unfortunately i have a problem.
i cannot connect to the WoW Circle 7.3.5 Legion server.

i did register an account, i have my management page on https://cpleg.wowcircle.net/
i downloaded the 50gb client, and i did follow the instructions from How to Start Playing here :
https://forum.wowcircle.com/showthread.php?t=803557

however, when i try to login, i get an error message : "unable to connect, try again later."

also, i looked for a realmlist.wtf file, but i couldn't find any, so i'm a bit confused about that. usually, there's a realmlist.wtf in the data folder... is it why i can't connect?

any help would be greatly appreciated please :)


EDIT :
i actually found the issue.
there's no more realmlist.wtf file in the data folder. it's different now, it's in the WTF folder : the config.wtf file. inside, the first line that says : SET portal, you need to add the following : "legion.wowcircle.me"
so the line looks like this :
SET portal "legion.wowcircle.me"

i can connect now. it works flawlessly.
