Check your private server settings
In Roblox, open Settings → Privacy and content restrictions → Visibility & private servers → Private servers. Check who can add you to a private server. On the Roblox website, Settings opens through the gear icon; in the application - through More (...) and settings. The names are based on the English reference and may differ in translation. For accounts under 13 years of age, the official section indicates the ability to log in only to private servers of friends; Don't change your age for access.
What should the owner check?
Ask the owner to make sure the correct username is added to Server Members or Friends Allowed is enabled for friends. The invitation must be for the same account you logged in with. If the game is intended for community members only, check the membership in the desired community. A regular link to the server does not prove permission. It is useful to complete this step before reinstalling the client.
If rights have already been verified
Completely close the application and restart your device, then sign in again. The server may be temporarily unavailable: check notifications for the game itself or its community and try again later. To control, compare another game and another available network. Record the results without changing everything at the same time. The official help also allows for network or temporary device errors, so the confirmed invitation does not explain every 524 case.
When to check the application
If restrictions, availability and network are checked, update Roblox; If necessary, use reinstallation from an official source for your system. First, make sure you have saved access to your account. The help has additional platform steps with local data - select only the help section for your OS. To contact Roblox support, prepare code 524, device, version, game name and a confirmed invitation method. This helps explain at what stage access is denied.
