Website On Siteground Stopped Connecting

I have a site on Siteground that is not connecting. I disabled the siteground security, caching, and AI plugin that siteground loads automatically and still it is not connecting.

This site was working previously. Here is the system report;

Hey @davidcuff

I tested the child site from a my test MainWP Dashboard.

It returns 403 with the familiar SiteGround’s 403 error page.

Disabling the SiteGround WordPress plugins won’t affect a server-level block.

Please see if SiteGround’s support team can whitelist your MainWP Dashboard’s IP/URL or the User Agent. They were able to do this successfully in the past.

You can find details about the ports and user agent in this KB: https://kb.mainwp.com/docs/what-port-and-user-agent-does-mainwp-use
