Periodical issues with connecting to shop, games, realms, achievements,etc. While internet works fine on anything other than Minecraft.

Frequent but random times where I cannot play with my brothers, connect to the shops, to realms, achievements, or anything other than my worlds. Will kick me and brothers out of worlds we are playing in together. It’s not our WiFi or internet, as any other program/ app runs fine. We have checked settings and consulted the internet for help, but no luck. All of our platforms are up to date for system and game updates.
