So a few months ago I unplugged my bitcoin node when it was running perfectly. So when I connected it again this week I had to let it sync to the blockchain again. Now you can see it's synced but I have several issues. It tells me to update the version when v0.19.0.1 is totally up to date. And if I need to update, how do I do it? Secondly I don't know but it says that my node is unreachable (I cropped out the IP address). How can I fix it?
