Problem with WordPress and Google Cloud Platform

Question

I deployed my site under Google Cloud, transferred my domain over to Google Domains from GoDaddy, and followed the steps in setting up DNS Cloud.

Now that I can't log-in to my temporary WordPress site to continue working on it as well as my domain right now showing some errors (after following the steps from DNS Cloud, I also want to revert the step where it tells me to put an HTML code as "Hello World." to verify if I do it right).

Any helps is appreciated!

Answer 1

This issue was solved by Google Cloud Support by running this command:

sudo rm index.html

After that site is back without the "Hello World" embedded to it (from following step 3.2 in setting up DNS Cloud).
