How can I troubleshoot Roblox error code 773 if it keeps appearing?

Start by checking your internet connection. Try restarting your router and modem. If that doesn't work, check the Roblox server status on their official Twitter or website. Clearing your Roblox cache and cookies, or reinstalling the Roblox app may also help. Finally, try playing on a different server or at a later time, as server congestion could be the issue.
