When trying to play RedM using a copy of RDR2/RDO purchased from Steam or Epic, you will currently receive the error "Error during Steam ROS signin (4000.210)" or "Error during Epic ROS signin (4000.210)".
This is due to changes on the Rockstar Online Services implemented by Rockstar recently.
We're still investigating and working on a client-side fix to support the new R* services, however, we do not know when this will be done.
There is no workaround for Steam/Epic copies. Game copies purchased and activated directly on the Rockstar Launcher are unaffected and will still work.
