Recently I have been getting these error codes on my computer for Minecraft windows 10 pe, my iPad had the same error codes but now its fine. And my computer is getting them for the marketplace and its not letting me see the servers. And people havn't been able to join me and it keeps saying unable to connect to world for some peoples worlds when they invite me. And it has been doing it for the last month or 2. It has not let meΒ see my minecoins I have on my other account when I was signed into it. Its not been letting me use the pack's I have bought with the Minecoin's. And its been blocking my chat to talk with people on Hive bedrock edition. I was never banned or mute on Hive.

The pictures show exactly what I see now in 1.14.20 when I open Minecraft and my internet is not connected. I do think the message that you have an account error coming up just b/c your internet is not connected is a bug. It is an inappropriate, misleading error message. There ought to just be an indicator that you are offline.
