Login Problem Tidal

Hi, I have a problem I don’t understand.
I have installed RoonServer as core on my Imac.
As Roon Remote I use my Iphone or iPad.
Since a few days I can’t communicate with my Iphone or
the ipad log onto my tidal account.
I always get the message that I have forgotten my login details.

But if I try Roon on the Imac it works without problems.
I have already uninstalled Roon from Imac and left only the Roonserver on it. It didn’t help - neither Iphone nor Ipad I can’t login to Tidal
register.

Only if I install Roon on the Imac it works without problems.

Can anyone help?

Sorry for the bad English, I use a translation program.

Found the bug.
It’s okay.
