Hi Stratos Nikolaidis, I am wondering if, either your issue has been resolved or anyone has got back to you to help or let you know what is going on. It has been over a month now and you have been very patient.
I am also receiving a similar error:
[Jul 28 16:49:32] Call to Wordfence API to resolve IPs failed: We received an error response when trying to contact the Wordfence scanning servers. The HTTP status code was [0] and the curl error number was [6] and the error from CURL was: Couldn't resolve host 'noc1.wordfence.com'
[Jul 28 16:52:57] Call to Wordfence API to resolve IPs failed: We received an error response when trying to contact the Wordfence scanning servers. The HTTP status code was [502] and the curl error number was [0]
Because I have set up email alerts to let me know if anyone has attempted to log in or use the lost password, this morning I woke up to 9,550 emails - yes, you read that correctly! 9,550 emails, to let me know how many attempts to access my site had taken place, over a 6 hour period.
Can someone help me please, I am getting nervous and am unable to even look at blocked IP's. thank you in advance.
