Running site without SSL

Hi, I have setup a site that don't have an SSL certificate for. Site is working fine but I can't send emails or get the keep alive scheduled tasks to run. I get "One or more errors occurred. (The SSL connection could not be established, see inner exception.)" in the loggs for both the email and keep alive task.

The store setting has the require ssl unchecked and the store url starts with http://

Is there any other setting that will force the scheduled tasks to require SSL?

Sending a test email works fine, it's only when the task is supposed to send that it fails so there is nothing wrong with the email account setup.

I am clueless :)

PS. Have tried to clear cache, restart application, restart app pool, restart iis site

The store HOST values need to be set corerctly for the tasks to run
What do you have that set as ?
For example the Store URL is http://testsite.com.au/
The Host Values are: testsite.com.au, www.testsite.com.au

What version of nopCommerce is it ?

What is the domain name ?

Thanks, I had not tried to set the host values since it said it was only needed for multi store setup. But I now did it and it still does not work. Same error message.

Version is 4.30 and the address is http://test.skandinaviskabokforlaget.se

Execution address in the log is: "http://test.skandinaviskabokforlaget.se/scheduletask/runtask")

Finally figured out the problem with help from this post: https://www.nopcommerce.com/en/boards/topic/74011/the-send-emails-scheduled-task-failed-with-the-one-or-more-errors-occurred#251085

I had to add my domain to the hosts file on the server.
