Sololearn compile error!
I have a problem with compiling java programs. Is always says me that: "An error occurred. Please check your internet connection!"
Perhaps the servers are too busy in some moment and the user's queues with slower connections are refused. Otherwise, you may wait on compilation stage a very long time. I mean, this message might be the other way to inform you to try again later. I'm not saying that this is true, just guessing.
but only with sololearn and only with java where is logic? //sorry, all are giving error without "web" app
it means your connection is very slow
