If your child sites hosted on SiteGround are failing to connect to your MainWP Dashboard, a likely cause is SiteGround Captcha.
Key indicators:
- Connection Test returns HTTP status code “202 Accepted”.
- Your Dashboard suddenly can’t reach multiple child sites specifically on SiteGround hosting.
You can’t fix this yourself through MainWP or your site’s settings. You’ll need to ask SiteGround support to whitelist your Dashboard IP (found in your Dashboard under MainWP > Server > Server IP).
Note: On some Dashboards, this might show a local IP (e.g. 127.0.0.1). If that’s your case, contact your Dashboard hosting support to get the correct public IP.
If you are not sure if SG Captcha is the culprit please open a support ticket with us, and we’ll quickly confirm it for you.
