I recently created a wordpress site using the automatically setup version gcp provides: https://console.cloud.google.com/marketplace/product/click-to-deploy-images/wordpress
The firewall it creates is allows ingress for tcp:80 on IP ranges: 0.0.0.0/0 Otherwise, I have the default firewalls that gcp creates and applys to all. All is fine with normal site operation.
I wish to backup/migrate the wordpress site, and attempted to use the All-in-One WP Migration plugin. However, I get an 'server error' when attempting to download a file from it. My best guess (and it is a guess) is that firewall rules are not allowing the file transfer. What firewall settings do I need to allow and/or how do I figure that out? What are the typical firewall options that get set for downloads?
Alternatively, if I am going down the wrong path for backup/migration of a wordpress site on gcp, please let know.
