Hi, I can’t add the site sampledomain.pl/blog to mainwp. This site is not a domain, but a directory. How to do it?
Connection test failed: Error message: HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1)

Hey @ewebas

Welcome to the MainWP community!

The site being installed in a subdirectory shouldn’t be affecting the connection.

In the previous reports of this issue, the causes were either expired certificates or the improper Cloudflare configuration.

​And are you using Cloudflare for the child site or the Dashboard site?
​
​Can you verify that the Dashboard and Child sites in question have valid certificates? You can use a third-party tool such as SSL Checker (SSL Checker) to check certificates.

Thank you for responding so quickly.

I checked the site in SSL Checker - everything is fine, we do not use Cloudlflare for the child site and the Dashboard site.

Thanks for checking that.

Would you mind opening a private Help Desk ticket so we can collect some additional information & investigate further?
