However, I don’t think that will help. With mod_security, it’s more about finding the specific rule that’s catching us. The best way to do that is to troubleshoot switching off rules in chunks. If you find a chunk that suddenly works, start checking each individual rule in that chunk for the one blocking us.
Alternatively, you can whitelist these IP addresses:
122.248.245.244
54.217.201.243
54.232.116.4
and this range: 192.0.64.0/18
Please note that we are constantly adding new hardware to our network to keep up with demand on our services. This means that these IP addresses could change (or be added to) at any time, and is why we discourage restricting XML-RPC access to specific IP addresses only.
