Minecraft – “Proxy lost connection to the server” error when attempting to connect to server

minecraft-java-editionminecraft-java-edition-servernetworkingtechnical-issues

Every time I try to connect to any server. I always get either, [Proxy] lost connection to the server, or a existing connection was forcibly closed by a remote host. I can't join any server! Can anyone help?

Internal Exception: java.io.IOException: An established connection was aborted by the software in your host machine

Is your internet enabled? This is the cause of a lot of multiplayer problems. Also, try checking to see if there is a program blocking Minecraft from using internet. I went a while with no multiplayer, and it turned out that my mom's thing was blocking servers from Minecraft! Try these, as I don't know any other ways.
