If they already fixed the API I gave it to “Activate Network Brute Force Protection” and it worked.
The same problem and my hosting provider (Knownhost) tell me that everything is fine with my SSL certificate and my hosting, which is by ithemes security that I seek to contact ithemes support to solve it.
they tested the: ipcheck-api.ithemes.com in SSL Checker and there certificate did not pass “This certificate has expired”
I have not been able to solve the problem.
