Problem with connecting to servers

[Nightmare_Ind]

like title says, I have a problem with connecting to servers. It doesnt matter wich modpack, that is why it is on the platform pagoda. everytime I try to connect I get messages like this:

 

internal client error: java.io.IOException: server returned HTTP response code: 503 for URL: http://session.minecraft.net/game/joinserver.jsp?user=Nightmare_Ind&sessionId=token:09a9e94627514ee09fbb6205177ae07c:42f1df44e0c945999aea38dfa20fd226&serverId=3dbd41eea5de1d2d (without the clickable url, just what is written)

 

please help!

 

EDIT: nvm I restarted my computer and it works now
