From past experience seeing other people's threads, either you have a MAC ban or your MAC address is hidden. You might want to disable any other network adapters that you've no use: Control Panel >> Network and Sharing Centre >> Change Adapter Settings >> Disable any other adapters other than your Ethernet/WiFi adapter you're using to access the internet. If this doesn't work, you might then want to post a thread in character issues: https://royals.ms/forum/forums/character-issues.55/
