Same issue here, client-side. I have no incompatible software, and disabled my firewall. Only one server is causing the error (but I know others are able to connect to it). It seems to be a WiFi problem, since I was able to connect to the IP through an in-server chat app on my Android using mobile data. I'm starting to think it may be an issue outside of anything Mojang can do, especially since it's been two years since it first started popping up.
I'd be curious to see if anyone else with this issue is able to connect using PickaxeChat or something similar with mobile data.
