[Ray Bailey]

Sorry, I posted this a WP.com first. I have configured the API and after I go through he steps to Grant Office 365 Permissions I get the following error:

Hi Ray,

There is a problem with your hosting server, please contact your provider and ask them to check the servers certificate. cURL is making a certificate check and failing.

Kind Regards,
Tim

I host my own server. What do I need to look at? It is hosted on a Windows 2016 and IIS. It has a valid cert issued by CertifyTheWeb.

Hi Ray,

I had this with a user the other week. I actually asked the developer Yehuda about it, as he is more clued up on that than me.

The specific error that you got, looking at the docs relates to:
The remote server's SSL certificate or SSH md5 fingerprint was deemed not OK. This error code has been unified with CURLE_SSL_CACERT since 7.62.0. Its previous value was 51.

This is a different certificate than your public HTTPS certificate from CertifyTheWeb.

In some cases, it may be that you are missing a CA certificate installed on your server – so installing/re-installing that might help.

If you could also share your site’s URL with us that’d be great. If you want to keep this private, you can mark the reply as ‘private’ and it is only visible to myself, you, and the developer/creator Yehuda.

Thanks.

Kind Regards,
Tim

That fixed the issue. Thanks!

It is just a template at the moment though 🙂

Hi Ray,

Thanks for confirming this issue is resolved. Could I ask what you did to fix the problem? Any information you provide could be massively valuable and helpful to others in the future too.

Site is looking good already, thanks for sharing! 🙂

Kind Regards,
Tim

I put the file downloaded from https://curl.haxx.se/ca/cacert.pem into C:\Program Files\PHP\v7.2\extras\ssl and edited the php.ini file and put curl.cainfo = C:\Program Files\PHP\v7.2\extras\ssl\cacert.pem

You then need to run iisreset from an elevated command prompt.

Thanks for feeding back Ray, that’s helpful!

Kind Regards,
Tim
