Houston Salsa Congress customers started receiving reports of emails not going through after September 29th.
Upon further inspection we found that under Tools -> SendWP there was an SLL Certificate error. “Last Result: cURL error 60: SSL certificate problem: certificate has expired”

our hosting service stated: You will need to contact the plugin vendor on this and share them the URL
https://www.sslshopper.com/ssl-checker.html#hostname=houstonsalsacongress.com
The SSL is configured and is working fine. If the SSL had any issue, your website would also show the Private connection error.

After further research it seems we arent the only ones experiencing the issues of emails not going out (despite email logs showing they were sent) and the SSL Certificate expiring. A few relevant links:

Hi there,

This is actually from the ca-bundle.crt file included within WordPress itself and not an issue with Event Espresso and it was fixed in WordPress 5.8.2, see here:

https://core.trac.wordpress.org/ticket/54207

The SSL is configured and is working fine. If the SSL had any issue, your website would also show the Private connection error.

Well, no.

The sites own SSL certificate is fine, however, the version of OpenSSL in use on your server I’m guessing it old (pre 1.0.2) as if it wasn’t this wouldn’t have been an issue. The issue here isn’t the sites certificate but the CA certificates used when your server tries to communicate with another.

Your site is running WP4.9.8, is there something that has prevented you from updating?

One solution (without updating WordPress) is to use this plugin:

https://wordpress.org/plugins/ssl-certificate-manager/

Which set your site to use the latest ca-bundle, however, I still recommend you look into updating your site.
