My VMs appear running in my instances list but won’t let me connect since yesterday

Summary:

I have created 3 VM in Oracle Free Cloud, 2 small ones with 1GB of ram and 1 large one with 24GB of ram. I don't know what happened to the small VM that won't let me connect through Bitvise. It should be noted that everything was working fine until yesterday. In the Oracle Cloud panel I get that the VM is working but when I try to connect it won't let me. I tried turning the small vps on and off but they still have the same problem. I checked to see if it was problems with the entire service
