Cannot issue Let’s encrypt certificate

As described in this forum topic, there is an issue with creating /updating Let's Encrypt certificates. The "lescript" project that is used in your module was updated to resolve an issue reported in this bug-report.

To be sure, the error we get is:

There was an error updating the certificate: HTTP Challenge for pbx.exampledomain.nl is not available. Whole response: {"type":"urn:acme:error:unauthorized","detail":"No registration exists matching provided key","status":403}

Could you update this module so that we can use Let's Encrypt again?
