License validation server not available

[zolnayag]

Hi,

Our firewall is blocking some the Event Calendar PRO servers. Which IP address should be whitelisted in order to use Event Calendar PRO?

Thank you for your answer in advance!

Hi Andreas,

Thanks so much for reaching out!

Can you try whitelisting the IP addresses provided in the following forum thread:

Let me know if that helps!

 

Thanks,

Hi Jaime,

Thank you for your tips, but it does not work for me.

I am whitelisting the TCP protocol for the following IP’s at the moment:
34.211.235.206
54.69.187.22
34.211.14.212
52.89.196.208
107.170.232.165
162.243.159.176
50.116.28.27

I am still getting the error message “Sorry, key validation server is not available”.
If I stop the firewall, everything works fine.

Any other IP or protocol?

Thanks,
Andreas

Hi Andreas,

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

https://www.dropbox.com/s/uwtntzssi47tkmi/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 if that helps!

 

Thanks,

Jaime
