I am unable to attach a license to a Joomla install of Acymailing 8.6.0
I am running Joomla 3.10.6 so not sure if it is due to an old version of Joomla or not.
Possibly it is due to a port not open.
Here is the error message: Curl error message: Failed to connect to www.acyba.com port 443 after 17217 ms: Couldn't connect to server
Thanks for any thoughts.
