I can't connect my site to the community

I get an error that says curl may not be enabled on my server. I have verified that it is. What else is keeping me from connecting my site to the community?

To check if the cURL PHP extension is enabled for your website, you can go to the Dashboard > System & Settings > Environment > Environment Information.

There you’ll see a section with all the PHP extensions that Concrete can use.
For example:

# PHP Extensions
[...], curl, [...]

Is this the way you verified that curl is enabled for your website?

@Pixelfixer are you using a recent version of Concrete? Versions < 9.3.2 can’t connect to the new marketplace

curl is there. I also checked using a php code snippet. Curl appears to be enabled.
