No connection to the child side


when creating a new website on my MainWP Dashboard I always get the error message: SSL certificate problem: unable to get local issuer certifcate.

If I deactivate the SSL verification I get a 404 error message
Does anyone have any solutions?

Thank you very much

Hey @Nils

Welcome to the MainWP community!

a) What response do you get for “Test Connection”?

b) Do both the child site and the Dashboard have valid certificates when checked on a third party site such as SSL Checker?

c) Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → Server, on the top right of the page.

Be sure to use the button like the one below; this button hides all your private information:


Pressing the button auto-copies the report to your clipboard then just paste it in a reply here.

Hey Bojan,

Thank you for your feedback.

a) Screenshots

b) everything is displayed correctly on the main page. The same applies to the child page, but this message appears:

The certificate is not trusted in all web browsers. You may need to install an intermediate/chain certificate to link it to a trusted root certificate. Learn more about this error. You can resolve this error by following Sectigo’s certificate installation instructions for your server platform (use these instructions for InstantSSL). Pay attention to the parts about intermediate certificates.

Thanks @Nils .

This message indicates a potential issue with the child site’s certificate.

Can you reach out to the hosting provider and have them look into it further?

Hello Bojan,

thank you very much, the problem with the SSL certificate is solved, but now I get the following error message:

Error 404 (Not Found) is not a MainWP-specific error. It is a common server error and MainWP is simply relaying it.

In this case, it appears you have a security rule set up that redirects visitors of your homepage to the login page.

Perhaps the site is intended to be viewed only by logged in users?

After the redirect, &bp-auth=1&action=bpnoaccess is present in the URL which appears to be part of BuddyPress.

Yes, it is a membership (BuddyBoss), know it works. It was due to the start page settings, thank you.
