Initialy I got a conection error while I was working on the project in a jupiter Notebook instance. Then I closed the tab and tryed to open it again, but it said I could not conect. Then I tryed restarting the instance. It succesfully stoped, but doesn´t start again "An unknown error has occured, Please try again later". I already waited for two hours, but still that problem. (I already tryed to contact the support, but linuxone.community@us.ibm.com doesn´t seem to exist anymore)
