Hello there, 
So the problem is, an hour ago my server was working perfectly, when I tried to start it, connected to the server, it said something like "MTA Client verification failed", I was confused, so tried entering one more time, I joined, but, after choosing a map, it say that it will go to random after  5 seconds, happens with every map, when I checked the console, I found many errors such as the mapmanager, here's a picture of it :
