Title: Wordfence Scan problem Last modified: August 24, 2016 --- # Wordfence Scan problem * Resolved [liquidity](https://wordpress.org/support/users/liquidity/) * (@liquidity) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordfence-scan-problem/) * I am getting this problem: * 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 [7] and the error from CURL was: couldn’t connect to host * I tried this: * Click to test connectivity to the Wordfence API servers * This connects to noc1.wordfence.com and shows you the status of the connection attempt. It is a way to verify that your server is able to communicate with our scanning server on both port 80 and the secure port 443. * If this test fails, please open a support ticket with your hosting provider and ask them to ensure that your server is able to connect to noc1.wordfence.com on port 80 and port 443. They may have to allow your server to connect through a firewall or configure a proxy to allow this connection. * I then followed up with my host and they confirmed that port 80 and port 443 are OK. * What should I do next to try to fix the problem? * Thank you. * W * [https://wordpress.org/plugins/wordfence/](https://wordpress.org/plugins/wordfence/) Viewing 15 replies - 1 through 15 (of 21 total) 1 [2](https://wordpress.org/support/topic/wordfence-scan-problem/page/2/?output_format=md) [→](https://wordpress.org/support/topic/wordfence-scan-problem/page/2/?output_format=md) * [Luis](https://wordpress.org/support/users/lemoreno/) * (@lemoreno) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordfence-scan-problem/#post-5972468) * Hello, * I’m getting this error as well.

They were able to connect 2 days ago, and now can not begin a Scan. Attached it proof that cUrl is installed and active. Have sent off a support ticket to Arvixe tech support to ask if they can identify the problem as well. Happy to supply any further investigative details that might assist. * Kind Regards, * Ed. * Thread Starter [liquidity](https://wordpress.org/support/users/liquidity/) * (@liquidity) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordfence-scan-problem/#post-5972590) * [@edwardcox](https://wordpress.org/support/users/edwardcox/), * Maybe it is an Arvixe problem then?
