Hello and welcome to the Community, @Dumbguy101!
Hmm, that error seems to suggest that there’s an issue with the SSL certificate for the WordPress website you’re attempting to connect to. Are you using a self-signed certificate? If so, that might be what’s causing the error as Zapier currently only supports SSL certificates issued by public certificate authorities.
Alternatively, it could be that there’s an issue with the installation of the certificate. Can you try checking the configuration of your website’s SSL certificate?
You can use a tool like Qualys SSL Labs for that: https://www.ssllabs.com/ssltest/
Looking forward to hearing from you on this!
