Can't Connect to server : No further Information

I'm trying to join my friend's aternos server, I was in his server a few minutes ago then I started lagging hard so I left the server but now I can't join back, minecraft won't ping the server or anything like that, all it says is the default minecraft server image and the title says "Can't connect to server" but before I started lagging I was able to join it, I've tried flushing my dns, changing my dns, trying the dyn IP, restarting minecraft nothing works, can someone help please? 🙏
