Ps4 Coop Error Code

I’ve been playing coop for a while now and suddenly I go to log in and my entire server is like frozen with an error code CE-34878-0. I can’t get into my server at all. An I’ve done so much I’m gunna be so upset if its gone. If anyone knows anything about about it pls lmk. An I already checked google for fixs so helpful comments would be great.
