Error; unable to connect to the server; shop.nexusthemes.com

Most likely reasons:
* An outbound firewall; contact your hosting provider and ask if they block outbound network activity from the webserver. If they do, ask them to whitelist the following hostname: shop.nexusthemes.com (without it, the discounter plugin wont be able to work)
* A temporary network issue; retry in 5 mins
