Panel does not activating due to license server unavailablity

Symptoms

When activating a license, the following error occurs «No license available for your server. Perhaps, the activation key has been already used or has expired. Perhaps, the installed version of the product was released later than the one to which the specified key allows updating».

There are errors «Got bad result from» and «Bad try: ONLYISPMGR» in the license module log file /usr/local/mgr5/var/licctl.log.

Solution

The licensing server has several IP addresses, as well as scripts for checking the license on these addresses.

For the licensing module to work correctly, access to the server via ports 80, 443 and 1500 is required. These ports must be open for incoming and outgoing connections to the licensing server at https://license.ispmanager.com/.

To check availability of the licensing server, execute the following command:

1. Make sure there is an up-to-date version of cURL installed on the server;
2. Execute requests to the following addresses using cURL:

curl -i -k -L -v https://86.license5.ispsystem.com/pricelist/soft
curl -i -v http://212.109.222.131/mgr5.45.state  
curl -i -v http://144.76.174.134/mgr5.45.state  
curl -i -k -L -v https://212.109.222.131/mgr5.45.state
curl -i -k -L -v https://212.109.222.143/mgr5.45.state  
curl -i -k -L -v https://144.76.174.134/mgr5.45.state 

A correct response to a request will contain the HTTP/1.0 200 OK line, which will mean the server is available.

If a request to any of the specified URLs fails, it will be necessary to verify and adjust the relevant network settings. We recommend you to contact your server's system administrator or your hosting provider's support team in case you use their services.
