Cant add website

I try to reconnect a website but it fails.
When I click Test Connection then I get this message:

Connection failed!

URL: - HTTP-code: 200 (OK) - Error message: Problem (3) in the Chunked-Encoded data

What does this error means? How to proceed?

Hi @alainL

There is a hook which may fix the issue with this child site:

​add_filter( ‘mainwp_curl_http_version’, ‘myhook_mainwp_curl_http_version’, 10, 3 );
​function myhook_mainwp_curl_http_version( $input, $site_id, $url = ‘’ ) ​{
​if ( $site_id == SITE_ID_WITH_THE_ISSUE ) ​{
​return CURL_HTTP_VERSION_1_1;
​return $input;

​Replace the SITE_ID_WITH_THE_ISSUE with the IDs of affected sites. You can find the ID by opening an individual Child site overview, and looking at the end of the URL.
​The hook can be inserted using our free extension Custom Dashboard, or by inserting it into the functions.php file of the active theme on your MainWP Dashboard.

How can I find the ID of a website that is not connected to the dashboard? The issue is that I can not connect this website to the dashboard.

Thanks for the update. My reply was based on the wording “reconnect” in your first message which made me think that the site is already added to the Dashboard, but that you cannot re-establish the connection with it.

Since you cannot add it, please open a private Help Desk ticket so we can collect some additional information & investigate further.

Thanks for the reply. It seemed I got blocked by Imunify360. After contacting the hosting the issue is resolved.
