Hello team. I have a problem with license. 

Error: "There was an error communicating with the IPS License Server: Connection timed out. Please try again later or contact IPS technical support for assistance."

How fix it?

Thanks.

Is anybody here?

Yes, loads of us are.

Have you raised this as a support ticket while waiting for a response on here?

On the off chance....maybe you are running PHP 5.6.3? http://community.invisionpower.com/topic/410113-php-563-ips4-error-communicating-with-the-ips-license-server/

I had this happen to me, I ran the support tool and it cleared it up.  Have you recently moved your forum to another folder on your domain?

​

What support tool?

No I haven't moved forum to another folder.

 

Is anybody know correct information of connection to license server?

Port

Protocol

URL

And other

In your ISP4 ACP, System Support -> Support -> Select "Something isn't working correctly."

That sometime will clear the issue but yes it may be with your firewall.  

They are typical ports 80 & 443 outbound but they do have specific subdomain.  Not sure if that applies but best to ask them on that one.

​I can't enter in my ISP, because I can't install it
