Hi Ryan,

Just wanted to close the loop on this as Andrew provided the necessary list to you via email and I see you confirmed receiving the email.

Kind regards,

Matt

Dear Matt,

we have the same problem and we also need the adresses and URLs for whitelisting. I uploaded the log file with the error message.

Kind regards,

Georg

We have a secure environment with firewalls blocking all internet traffic. To allow Pinnacle 21 community 4.1.0 to function it looks like it requires internet access to some things. We need to make an exception to allow the program to be used from our environment. Can you please provide me with the IPs and URLs needed to connect to your authentication server/s as well as any IPs or urls for additional services that are required?
