I have a ue40ku6400 - Disney + has been working fine for a few weeks but now I am getting this (no problem on another Samsung TV)
The error message relates to 'language settings' for what that's worth
I have been through disney + support & tried various things to no avail including verifying password, changing DNS settings etc.
Reinstalling smart hub worked until TV powered off then problem returned. Any ideas gratefull received - no one else seems to have this error!
@Saint_Nick , Cheers! What's the full software version on your TV?
(Menu / Settings > Support > Contact Samsung / About This TV)
@Keiran25 , With us being UK/Ireland based we're limited on what support we can give for US users, but it would be interesting to know the model code and full software version of your TV too. 👍
