[PC] Mass Effect Online Access Error in Multiplayer Mode

I appreciate your help, but unfortunately it didn't work ☹ I run the repair, and when that didn't work, I re-installed the game on the same drive as the EA app, which is the system drive. Also deleted the license file and temp folder. Still, the issue persists. Does the game require a specific install location, DLCs (only installed multiplayer DLCs), admin rights or a specific port or anything I could possibly be missing?
