Hi i use ispconfig 3.2.9 I have a few wordpress websites and i have a plugin for newsletters and its giving me this error Test failed: cURL error 60: SSL certificate problem: self signed certificate Report this error to your provider saying the site cannot make an HTTP call to its wp-cron.php file and copying the error message above. what do i do? I am using the free Let's Encrypt SSL in those domains Thank you in advance. Ben
I guess you get this error when you try to send a newsletter? In this case, check the email send settings in the plugin, you must use the hostname of your server and not the domain of your customer as smtp server domain.
it ended up being my pfsense router, i had to do this: make sure in pfsense under System -> Advanced > NAT that following are set: NAT Reflection mode for port forwards: NAT + Proxy Timeout: 10 (what ever you want) Enable NAT reflection for 1:1 NAT: checked Enable auto outbound NAT for reflection: checked that cleared up all loopback errors, curls error and cronjob errors.
