Hi,
This message usually means that the Securitycheck extension (or another security/firewall extension on the site) is blocking Route 66 when it tries to access the page.
For reference, Route 66 simply uses your server’s PHP environment to request and analyze the page content, similar to a normal internal page request. If Securitycheck has any firewall, URL filtering, or exclusion options, it would be worth adding exclusions for Route 66.
Also, please check the following:
If the issue continues, please let me know which exact page URL triggers the error and whether disabling Securitycheck temporarily changes the behavior.
Best regards

Hi,
Great, thanks for the update.
This confirms that Securitycheck was blocking the requests made by Route 66. In this case, whitelisting your IP solved the issue because the page analysis requests are executed through your current session/IP.
Ideally this should not be necessary, but it depends on how aggressively the security extension is configured.
I’m glad to hear it’s working now.
Best regards
Lefteris
