 * Hello,
 * Hopefully, this message finds you well.
 * Thank you very much for this great plugin. Unfortunately, it is incompatible 
   with All-in-One Security (AIOS). When it is active, MainWP cannot connect to 
   my website.
 * Could you please advise me which settings of AIOS should be disabled?
 * Thank you in advance.

 * Hey [@denizci88](https://wordpress.org/support/users/denizci88/)
 * These are the likeliest security plugin settings that might interfere with the
   connection, so please see if they are enabled and try deactivating them temporarily
   to identify the cause:
    1. Cookie based brute force prevention
    2. Firewall allow list / Login whitelist
    3. HTTP Authentication
    4. Blacklists and lockouts
    5. Visitor/Site lockout

 * Hello,
 * Thank you for your reply. I deactived them, but the issue is still in progress.
 * Maybe we should accept “incompatibility”
 * Thank you again.

 * Hey [@denizci88](https://wordpress.org/support/users/denizci88/)
 * We were unable to reproduce the issue with AIOS with those settings disabled.
 * Can you establish a connection when you deactivate AIOS plugin?
 * Also, please feel free to open a private Help Desk ticket and we will gladly 
   look into this: [https://mainwp.com/my-account/get-support/](https://mainwp.com/my-account/get-support/)
 * We have an internal tool that lets us see the response message from the Child
   site. Usually, it helps identify which security rule is blocking the connection.

 * Thanks for opening the Help Desk ticket.
 * We were able to confirm that this was not a general incompatibility between MainWP
   Child and AIOS. The MainWP Dashboard server IP addre
 * ss had been added to the AIOS Permanent block list. After removing that IP from
   AIOS → Dashboard → Permanent block list, the site reconnected immediately.
 * For anyone else running into a similar issue with AIOS, please check:
    - AIOS → Dashboard → Permanent block list
    - AIOS → Dashboard → Locked IP addresses
    - AIOS → Firewall → Block & allow lists
 * Even if the Dashboard IP is allowlisted, the Permanent block list can still prevent
   the connection.
 * I’ll mark this as resolved.
