Using the promotionals credits (the 300$ opening account promotion), i used to connect my VM using SSH gcloud compute ssh instance_name all was fine.
End of promotional credits, i linked the project to my billing account. Then now, running the same SSH connection return this error
ERROR: (gcloud.compute.start-iap-tunnel) Error while connecting [4033: 'not authorized'].
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255].
I don t get it... the VPC is fine, the firewall got all ports open.
Do i really have to set an iap tunnel ? Why the normal SSH connection is not working anymore ?
Thanks if someone can confirm (before i change what was working well).
