Interestingly, in the case of the mail send schedule for example, it seems that only the runs done via schedule fail, the ones that are manually started appear to go through fine.  At least they do not raise an error log.

Hi,

Make sure the Store URL is correct. You can find this setting in Configuration -> Stores.

Hi, thanks for the response.  Problem solved.

In my case it could not resolve the hostname of the website from within the server.  The hosts file contained the ip address for the external IP address and not the internal so would never have resolved.  Once the hosts file was fixed up we're all good.


Cheers,
Paul

Can you explain how did you resolved this issue, I am also getting this issue.

especially this thing

The hosts file contained the ip address for the external IP address and not the internal so would never have resolved.

I had the same issue in which I resolved as well. We are self hosting our website at our office. Let's say our website is "www.website.com".

Our ISP provided router does not allow Loopback. Inside the office, we cannot access "www.website.com". Since we are a small office, we modified the "hosts" file on everyone's computer so "www.website.com" would resolve to the internal IP address of the server / computer the site is hosted on.

However, we did NOT do this on the server hosting the site itself. We modified the "hosts" file, so the address of the server / computer the site is hosted on would resolve to the internal IP address of the server.

This solved our problem.
