Lost 12 of my 16 Websites


i lost 12 of my 16 Website Connections,
the most of them without any security plugins.

When testing the connection, sometimes it says ok, sometimes it says, that there is no mainwp-child plugin installed.

Is there someone who could have a look at this?
My report:

Is there nobody, who can help?

Hi Marvin,
Are they all on the same hosting provider or server?
Maybe a firewall issue and you have to whitelist the IP of your MainWP Dashboard?
I got this issue with 50 sites and they were all on our prefered hosting provider. The firewall was at the servers level so they whitelisted our IP address…
Hope it helps.

Hi Frederic,
no, they are Not on the same Server / hosting Provider.
So i have to go to All clients Server and add the IP of the Mainwp Server?

Hi, Sorry for the delay of my answer…
You can try at least one or two to see if it fixed the issue…

Hi Marvin, it might be good to increase WP Memory Limit on your MainWP Dashboard too. Also, is there some security or caching plugin in common for all sites that get disconnected? Do you use some Cloud Proxy like Cloudflare for these sites? Is there anything in common for these sites?
