cURL error 7: Failed to connect to marketersdelight.net port 443: Connection refused

[jjj]

Bug description:
When logging into the backend of the WordPress site www.beambackpack.eu I get the following message: cURL error 60: SSL certificate problem: self signed certificate

In the first instance, I contacted the hoster. They came up with the following conclusion:

Unfortunately, it took a bit of figuring out because a process on the server was trying to connect to an external party. However, that server does not respond.
When I log in, a connection is established with an IP address from another provider
(Linode):
46913 connect(9, {sa_family=AF_INET, sin_port=htons(443), sin_addr=inet_addr("66.228.36.30")}, 16) = -1 EINPROGRESS (Operation now in progress)

I blocked it, hoping that no error message could be generated about it, and so the wp-admin would just load.
Instead, I got the following message, with a little more information:
cURL error 7: Failed to connect to marketersdelight.net port 443: Connection refused
If I try to visit it in my browser:
marketersdelight.net didn’t send any data.
ERR_EMPTY_RESPONSE

Website URL/page affected:

https://www.beambackpack.eu/wp-admin/

Current WordPress version: Difficult to find out, as I do not have access to the backend.
Current MD version: Difficult to find out, as I do not have access to the backend.
Error notice (if applicable): See above

Hi @jjj sorry for the late reply here.

I see this is an old version of MD as it is trying to connect to the now defunct marketersdelight.net domain.

If you have FTP/server access you can disable the request. If you are willing to provide me with FTP details I can quickly do this, otherwise you will want to look around the /lib/marketers-delight.php file and remove the include() statement for updater.php.

Hi Alex,

Thank you for your response. That was indeed the problem. I can now log in again.
