Hi there,
This is a recurring issue with OVH, unfortunately.
I’ve spoken to our host (Kinsta) about it. Apparently, their servers (Google Cloud Platform) receive a ton of malicious traffic from OVH servers, so many of them are banned on the Google servers. In most cases, they’re happy to remove these IPs from the ban list, but that’s not the case with these OVH IPs. Due to the amount of malicious traffic their servers receive, they aren’t even allowed to temporarily allow them.
Ideally, this is something that OVH should reach out to Kinsta about, as OVH should be concerned about malicious traffic coming from their servers.
From our end, there isn’t much we can do unless we want to move to a completely different host that isn’t using the Google Cloud Platform.
This doesn’t mean you can’t use GP Premium with OVH, it just means you’ll need to manually update the plugin until they’re able to resolve the issues.
