XML RPC SSL Issues

Hello.

I’m running multiple wordpress sites on Digital Ocean, and all have certificates from LetsEncrypt.

It’s a droplet running an ordinary LAMP stack, no configurations blocking or disabling xml-rpc, and if I browse to the xml-rpc.php I get a 405 Method not Allowed error, probably due to it being a GET and not POST request. That is with both https:// and https://

https://xmlrpc.eritreo.it/ shows that there’s no issues with accessing my xml-rpc protocol. Image of the test

The WordPress.com dashboard is unable to connect, and the debugger in JetPack says it’s not accessible.

That makes me think that the issue itself is on JetPacks end, correct assumption?

This is the information from the JetPack debugger, which doesn’t help much at all.

It looks like your site can not communicate properly with Jetpack. ?
