Can't load into friends local hosted server

So I have been playing Space Engineers for nearly 1,000 hours now. I have been playing on a long term server with a large group of friends. I live in the US and he lives in the UK. I had a old Omen PC that I played with and it worked just fine for a while. Recently I got a new PC a massive upgrade, I got everything installed and set up and now when I try to load into my friends server 1 of 2 things happen. Either my game will freeze and I can't do anything, so I have to tab out and close the game. Or I load into my friends server but the game says it's paused. I have left the game running for an hour when both of these things happened and nothing came of it. I have uninstalled and re installed the game. I verified the integrity of the game files. I have uninstalled all my mods and updated my system and graphics card. Nothing helped to fix it. The server that my friend is hosting is modded but that has never been an issue before. If I would have some help fixing this I would love if you could, the server I'm trying to join we have spent about 200+ hours of work into and I would like to be able to play in the server again.
