How do I resolve a connectivity issue to Google Cloud using SSH?

Question

I am doing my first project on Google Cloud, accessing SSH using the SSH dropdown on my VM instance and was going through the steps to set up the environment to use FileZilla to copy my project, apparently, I waited too long as I was setting up FileZilla and my SSH session timed out. Since then every time I try to access SSH, I get the following error message:

Code: 1006 Please ensure you can make a proper https connection to the IAP for TCP hostname: https://tunnel.cloudproxy.app You may be able to connect without using the Cloud Identity-Aware Proxy.

This started happening around midnight last night and still going on this morning. I have searched and followed all the instructions pointed out on this link:

https://cloud.google.com/iap/docs/using-tcp-forwarding

and the problem persists. I have even stopped, started, and reset the VM instance which did not resolve the issue. I am hoping someone has any other suggestions I can follow beyond what can be found on this site already.

Thank you in advance for any help and suggestions.

UPDATE:. I still haven't found the solution, but I have found a way to access my instance through my local terminal on my MacBook using the gcloud command from the Google Cloud SDK.
