We have a customer that is unable to activate their license because they always get “Failed to connect to the server due to network error” messages. We know that they have a proxy in place. We added code that allowed them to manually set the proxy, but they still cannot connect. The return from LexActivator (Java) is not giving enough detail for us to determine what is wrong. Name lookup? Connection? Something else?
What are the next steps for diagnosing the issue? These are our current diagnostic steps:
First, test the status of the CryptLex servers by browsing to
https://status.cryptlex.com/. Verify that the “Web API” item has
a green check mark. Also check that the “Web API Response Time” is
less than 1000ms.
Second, check to see if the client machine can connect to the
CryptLex server by bringing up a web browser on the client
machine, and connecting to https://api.cryptlex.com/v3/users. If
“Authentication failed!” is displayed, then the test was successful.
If this test fails, then most likely there is a very restrictive
firewall between the client machine and the CryptLex server.
Therefore, the firewall may need to be configured to whitelist
outbound connections to api.cryptlex.com (126.96.36.199 and
188.8.131.52) for port 443.
