The Laserfiche 12 installer has a Firewall/Proxy Information section at the very top of the first screen with a Verify button. We are getting reports of errors from all source networks around the web. The environment does not appear to be a factor.

I did some digging on my network and I found the following:

These are the endpoints that consistently can not be reached.

We can reach them using a web browser though.

If we monitor the network traffic while using this verification button we see an immediate SYN, ACK response acknowledging our request and the software continues to do a cipher exchange and send and receive application data.

I feel we can reach these endpoints (websites) and need guidance on what to do next.
