Defender and Hummingbird Page Cache

When my clients are trying to access my site they are reaching a cached lockout page.

I’ve tried to remove all blacklisted IPs and even deactivate Defender, but this didn’t help.

It appears that Hummingbird cached lockout page and shows it to all my clients. So I had to deactivate Page Caching in Hummingbird.

Let me know if there is any hotfix for this issue.
