In my case this seems to because I created a Microsoft account with a child's date of birth, then changed it to an adult birthday - because permissions were not working... That actually fixed the problem for a while, then something changed and I started getting this error again.
According to Xbox support, the birthday used to create the MS account is copied to the XBL account when it is created, and can then never be changed. It doesn't explain why I couldn't give a child account permissions to play online servers in the first place, or why changing birthday fixed it temporarily.
I've spent hours logging in and out of xbox app, xbox site, Microsoft live, xbox site etc etc trying to fix this for "Awzaw JD", an adult account with full permissions currently unable to even see online servers, nevermind play on them.
Xbox Support eventually suggested I just make a new account, but I know many kids with this problem on the public servers I manage who don't want to lose their Gamertag, and even more whose parents don't have time to search through family and child permissions settings.
I'm on a 200Mbps FTTH connection and have the same issue across multiple android and iOS devices. My main adult account works fine.
