I can't ssh into my LAMP server

[Fred-Niyi]

Firewall ingress rule allow port 22 from 35.235.240.0/20.

Firewall ingress rule allow port 443 from 0.0.0.0/0.

Firewall ingress rule allow port 80 from 10.1.0.0/16 (my vpc network). After seeing the console output, I opened port 80 to 0.0.0.0/0 but got the same result, could not login to ssh.

I have 2 vms in us-east1-b behind a cloud NAT. One is a lamp stack, and one is not.

I can't ssh in the lamp stack but I can ssh in the non-lamp stack.

Even when I add an external Ip to the lamp, I still can't ssh. 

I have OsLogin and tunnel through Iap enabled project wide. 

At first, after configuring the lamp, I could ssh w/o issue, but sometimes take long. However, since yesterday, I could no longer ssh.

I deleted the lamp but kept the disk and then create a new vm and attached the disk to the new vm and still have the same issue.

Attached is output of the console 1. 

Kindly advise.
