Dead Mudfish Node

I was fine using mudfish yesterday but when i login today it kept on prompting the error dead mudfish node. I tried restarting, updating to the newest version and changed my node but the problem still persist. Please help

The mudfish server has a problem and cannot connect at this time. We recommend connecting to another mudfish server.

I tried all these nodes but the problem is still the same
