Sorry, key validation server is not available

[Erroll]

Hello,

We have both The Events Calendar (Version 3.9.3) and have purchased The Events Calendar Pro (version 3.9.3). When I login to WP-admin and try to activate the license for The Events Calendar Pro I receive this error:

“Sorry, key validation server is not available”

I have tried the following:

Tried to validate the license key in both Internet Explorer and Firefox.
Ensured there are no spaces in the license key

I have ensured that both versions of The Events Calendar are activated.

I have tried multiple times today to validate the license and each time I receive the same error.

The site is a Dev site located at http://bulletproof.azurewebsites.net

Hi,

Sorry for the issues you are having. I can help resolve this with you.

Please note the license keys are not needed for the plugin to work, they are only needed for automatic updates.

To get some information about the issue can you please try downloading this simple plugin called Validate URL:

https://www.dropbox.com/s/nyugz86o4401ayg/validate-url-.7.zip?dl=0

After Activating go to Tools > Validate URL

Enter in these two urls:

https://theeventscalendar.com

https://tri.be/

As well as these two IP addresses:

https://162.243.159.176

https://50.116.28.27

And let me know the response code you get.

If none of those are able to connect it means the site is blocked from accessing our servers and you would have to whitelist those ip addresses or check the connection if no sites are accessible such as https://google.com from the validator url check.

Let me know what you find out.

Thanks

Hello Brian,

Thank you for getting back to me. Here are the responses for each of the sites you requested me to validate:

It appears that https://theeventscalendar.com, https://162.243.159.176, and https://50.116.28.27 are failing with various error messages:

Error Found ( error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol )
Error Found ( error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol )
Error Found ( SSL: certificate subject name ‘*.tri.be’ does not match target host name ‘50.116.28.27’ )

If something needs to be whitelisted in our firewall I can have our team do that.

Again thank you for the help.

Thanks for the information.

Couple questions does you site have an ssl and is your server running on Ubuntu and if so what version?

Thanks

[Erroll]

Hello,

Yes the site does have an SSL certificate which is valid from January 12, 2015 to January 11, 2017. I believe its hosted on a Windows Server.

Thank you,

[Brian]

Thanks for the information we are still unclear on the source of this issue, but working to resolve it.

Please note your site will function without the license keys, but you will have to manually update the plugins.

[Erroll]

We appreciate any assistance on this matter. I just tried to validate the license again and again I get this error:

Sorry, key validation server is not available.

[Brian]

We are still looking into the issue. It is a very rare bug and we are still not certain on the exact cause.

We will update this ticket once we have more information.

Please note that the plugin works without the license keys and only the automatic updates will not work.

Hello,

This morning I logged into our WP-Admin and the Key shows its been validated:

Valid Key! Expires on 2016-04-28

Thank you for your help.

Cheers

[Brian]

Great glad it working now.

I am going to close this ticket, but if you need anything else related to this topic or another please post a new topic on the forum and we can help you out.

Thanks
