(Background info : ps 1.16.1 me 1.16.2 optifine happened around 2:03 AM GMT today)

As the title suggests I have been playing a playerserver for the past week or so and have always been successful. Then one day when it was just me on the ps (remember the server belonged to him so that could have caused something bad to have happened) I was kicked and sent to the main lobby. This usually happens a few times a day so I was unfased and just did /join as I would normally and waited until I got on. This time however I got to the loading terrain screen and immeadietly got the message "[Proxy] Lost Connection To Server" and every time I have tried to join since. I tried changing my game to normal 1.16.2, 1.16.1 and optifine 1.16.1 but still nothing. I've restarted my wifi, my minecraft, my computer, and still nothing.

Any assistance would be greatly appreciated,
