Following up…
I am sorry, but I do not wish to publicly disclose my IP address. Also note, I am not using Securi. Everything in my log post with a ?? is direct from the log. I only changed the domain name and IP.
My server uses Imunify360; no Cloudflare. For plugins, I use Wordfence for security and LiteSpeed Cache with compatible server.
I do not have this issue present so long as I do not update the plugin. I think that perhaps the ?? being blocked from non-crawlers is what may have changed between versions.
Based on the log I do see that I appear to be switching between two IP addresses. While both are assigned the correct ISP, country, city and state when checking the IPs, I see that one has ?? in most of the query and the other has the needed data. I am not running a VPN or proxy either on my computer or on the model/router, so I can only assume my ISP is doing this.
When logging into the modem/router, which is ISP supplied, I confirm that the DHCP is based on the IP that has ?? and not the other with data. The two IPs are not from the same set; the first six number do not match, for example.
The ISP is Cox Communications West.
