HTTP error - empty reply from server

I’ve just noticed that all 6 of the sites I have using MainWP have stopped syncing (all on the same date) and when I try to reconnect all I can get is “HTTP error - empty reply from server” response.
I have no idea what’s wrong except that UpdraftPlus is showing a scheduling error as well.

Total newb here so any suggestions would be a great help. My webhost isn’t much help at all and just sent me here anyway!

Thanks

Ade

Hi Ade,

Can you tell me what response do you get from the Test Connection feature if you test one of the disconnected sites? Something like this can happen after the server firewall (or some other security layer) starts blocking requests from your dashboard.

Hi Ade, thanks for verifying vie email that the problem was caused by ModSecurity.
