Edit: I have a 10GB VM. I’m thinking I’m out of space. Does this make sense?
I have been working on a WordPress (deployed using GCP onto Debian 9 OS) site for the past week, after setting up an external static IP, and all was fine till this morning.
Last things I did last night were to edit some text (which updated to site just fine) and to upload a dozen images (each 2 MB in size) via wp-admin for use in a post, just before bed.
Woke up this morning with an upload error--not all files uploaded. Also, I could not save any subsequent changes from wp-admin. I could no longer access the site from my browser, or my phone. The browser either completely hangs or I get a server stopped responding error.
I can ping the website's IP with success even as we speak.
I logged in to GCP and restarted my VM, but that didn't fix anything.
More than that, I cannot SSH in as before. After many many minutes, I get this error:
"VM guest environment outdated The VM guest environment is outdated and only supports the deprecated 'sshKeys' metadata item. Please follow the steps here to update."
Not sure why I am guest now.
Launching phpmyadmin and wp-admin from the browser all spectacularly fail with "waiting for..." and then a server (408) timeout.
Bear with me, I am new to GCP and WordPress hosting, but I can't imagine how editing a post can cause this rather catastrophic turn of events. Something weird happened elsewhere. I have not been monkeying around with any settings via SSH, or even using GCP console prior to this event.
Note: I am using the Free GCP plan at the moment.
