I cannot validate the API Key, how to solve this?
If you ever received this message,
Your firewall may be blocking us. Please contact your hosting provider and ask them to allow connections from your site to api.shortpixel.com (IP 184.108.40.206)
then it is caused most likely by some firewall restriction in place, that only your hosting provider can assist you with. To be more precise, the outgoing connections from your server (where you have your website hosted) to our API (port 80 or 443) are not being allowed.
You can easily check if this is the case this way:
- Install and activate the plugin WPTerm on your WordPress site.
- Go to Plugins, look for WPTerm and then select Terminal.
You should see an interface like this one:
On that interface, write these two commands
telnet api.shortpixel.com 80
telnet api.shortpixel.com 443
and you should see the results of these commands looking like in this example:
If you cannot replicate the output as in the example above, then please go ahead and contact your hosting provider letting them know about the outgoing restriction from your server to api.shortpixel.com (port 80 or 443), and they should be able to assist you.
