I can't access the Online Server

[Edgar Grolles]

Since yesterday, I can no longer connect to the online server. It tells me every time: Account error.
Just before, I merged my Asmodee account with another account I had created by mistake a few years ago. It didn't have any impact on any of my many Asmodee games. And, on Ascension, I have all my extensions, I can play solo, everything's fine.
Except when I want to connect to the online server...
