I signed up for google cloud and recieved 300$ free trial. Recently I wasn't able to ssh into my instance. So I checked the google cloud console and found a message showing you must Enable billing to use further. Now I can't associate my project with the free trial account which has 285$ and 45 days remaining.[Also the number of days left has drastically reduced from 55 to 45 after this]. When I look into the free account it shows closed.
