Yesterday (Friday 6 March) I received an alert email from AwareIM:
There is a connectivity problem with the licensing server. The softwre will stop working in 5 days . Please check your Internet connection. If it is working fine NOTIFY YOUR SERVICE PROVIDER ASAP.
Is this due to a specific issue on my own server or is there are a general connectivity problem with the AwareIM licensing server or (as earlier) the Cloudflare services?
I should note that I recently changed my server structure: I installed an additional Linux server which has NGINX running and this server is now acting as the reverse proxy server for the Windows server on which AwareIM is running. Consequently, I changed the domain name to point to the reverse proxy server instead of the Windows server.
However, from the Window server I can make connections to other websites using http and https, so it does not seem that there is connectivity problem from my server, with regard to outgoing connections.
