How to fix LA_E_INET error from ActivateTrial()

My app uses the ActivateTrial() API function, but this is failing for one of our customers.
On their system, this returns error code 48, which is LA_E_INET.

I’ve tried to diagnose this with them, but as far as I can tell their internet connection is up and should not be blocking any traffic to the cryptlex licensing servers.

I’ve also asked them to try and access this URL from their browser, this is successful and returns the correct response:

What else can we investigate to try and fix this?

Hi Francis

please see the link below to help with your question and let us know if you have any further queries

I think my case is different to this other forum post.
Our application is not in development, it has been in use for over 2 years now in the wild.

This error is happening for just one customer, so I think it must be related to their network configuration somehow.

Hi Francis,

We recommend to disable the antivirus or any firewall before proceeding. They might block it at times.

Also try using the latest version of LexActivator.

If you could share the log of the network tester shared in the previous link, it will exactly tell us what is blocking the request.


The customer is on macOS, so your network tester app will not work.

I will check the lexactivator version and report back.
