Cannot connect Discourse to WordPress

I made api key, typed url, api, username, and this is what I get from the WP Discourse plugin.

You are not connected to Discourse. Check that your connection settings are correct. If the issue persists, enable connection logs and check Logs.

And this is the log that I get.

[2022-06-05 17:20:38] connection.INFO: check_connection_status.failed_to_connect {“error”:“wpdc_response_error”,“message”:“An invalid response was returned from Discourse”,“http_code”:"",“http_body”:""}

And sometimes this log.

[2022-06-05 16:14:55] connection.INFO: check_connection_status.failed_to_connect {“error”:“wpdc_response_error”,“message”:“An invalid response was returned from Discourse”,“http_code”:404,“http_body”:"\r\n404 Not Found\r\n\r\n<h1>404 Not Found\r\n<hr><center>nginx\r\n\r\n\r\n"}

I also check curl and this is what I get.

curl: (60) SSL: no alternative certificate subject name matches target host name ‘
More details here: curl - SSL CA Certificates

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

What should I do in this situation?

Hey @CMASFO, welcome to meta :slight_smile:

For this kind of issue please see my response here

In particular:

I’d recommend you press your hosting provider a bit more, asking them why there’d be an inability to make a cURL request to a domain. If they have some more specific reason to think it’s an issue with the WP Discourse plugin, and not say, an incorrect cURL version on the server (which on the face of it is more likely), they’re welcome to post here, or even pm me, and I’d be happy to look into it further with them.


Let me know how you go with those.


I experienced this problem from 2 environments.

one was bitnami wordpress stack, and the another was aapanel.

so I just tried to install wordpress manually,
like installing server and database by hand,
and now it works!

just wonders what the problem was

thx for replying


It was most likely the version of php-curl on your server.
