Are you playing on a wifi connection or a mobile connection? Mobile connections is not very stable to play online with minecraft.

Check if your account settings allows for multiplayer on the website under online privacy and safety settings.

Xbox Live Gold will work with all Xbox consoles from the Xbox 360 up to the new Series X/S. So you have no problem there with Gold. Minecraft for the Xbox 360 however will only work online with other Xbox 360 consoles. That's because the Xbox 360 version
is no longer updated and is not cross play with other devices such as mobile and tablet. If you want to play with your mates online, you will either have to use a different Xbox console, such as the Xbox One or a mobile, tablet, Windows, Nintendo Switch or
PS4.

The cross play of Minecraft works as such,

The PC/MAC is separate from the other versions in terms of cross-play. As in the only way to join a game with console or mobile players (or Windows 10) is to play on a realm.

Console (Xbox and PS), Mobile and Windows 10 will all work without needing realms as long as your friends are online or on the same network as yourself.

It is only the PC/MAC version of the game that will require you to use realms to join each others game.

Usually when i receive this message on my phone i just restart the app/game. It disappear after the restart.

Note that you will need to be connected to a wifi network as the mobile networks tends to be weak for online gaming from a mobile phone for Minecraft.
