How to I fix error 103 on xbox on roblox ?

Hi, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regards to your concern.

I have tried to check the error code on Roblox's support end however there is no related article, since this is an in-game error there is no option for us to validate but no worries because I have also investigated and this may be due to the account settings or maturity of the account.

You may need to manage some settings. For you to manage it you can simply sign in to https://account.xbox.com/settings.

If the system detects that your account is a child account you will be redirected to a support site and if not you will be able to change it successfully.

If you were redirected to a support page, please sign in to https://account.microsoft.com/family and check if there is an organizer account linked to your account then use the organizer account so sign in to https://account.xbox.com/settings then "allow" the setting on this screenshot:

I have tried what you said due problem still occurs

Hi I tried to setup the account for minecraft realms access but I can't get into xbox access.

Please help. Thanks

In this case, you may need to reach out to Roblox Support in that way they can check it for you.

Good morning ShaelynS ymons,

Just to throw some information at you.

Roblox's 103 error code through Xbox
This error comes a lot when Roblox's account is an under 13 rated account. Roblox has certain abilities you can do as an under 13, example, cannot use chat and unable to play certain games due to its content. Usually you'll get a warning sign if you're on the Pc/mobile version but you'll get an error 103 if the Roblox account is under 13. (If it's not to do with Roblox, it may be to do with your Microsoft family as previous commented by Francia)

A fix around this:
For this attempt of a fix, you'll need to make a new account, over 13 to be able to access content. If you're under 13, you're unable to and should be advised to be on mobile / pc monitored by a parent.

I hope this fixes the issue,

Sparrow
