 * Hello, following the latest updates, many websites are no longer connected, with
   this error: HTTP Error – Unable to resolve host: xxxxxx.
 * These websites are accessible on the web, however, with valid and active domains.
   
   What’s going on?

 * Hey [@momo-fr](https://wordpress.org/support/users/momo-fr/)
 * What error message do you get when you try to reconnect them in the MainWP Dashboard?
 * Did you make any big changes on these websites (e.g. configuring new security
   plugins that might block the connection)?
   Or were there any changes done on the
   hosting side?
 * As always, please make sure you’re running the latest versions of MainWP Dashboard
   and MainWP Child plugins.

 * Hi Bojan, the message is always the same: HTTP error – Could not resolve host:
 * This happens with different hosting plans (OVH, O2Switch, Infomaniak).
   The sites
   I have access to only receive updates, no new extensions, no specific changes.
   I have sites on the same node and hosting plan that aren’t recognized, while 
   others are.
 * I managed to reconnect 3 websites by redoing the MainWPChild configuration and
   I see this morning that they are no longer recognized.

 * It’s been some time since we heard back from you.
 * I’ll assume that the issue has been fixed and mark the thread as resolved.
