Licensing Error: Your computer is unable to access the activation service.

Alteryx Alumni (Retired)

What does this error mean?




As we transitioned to a new licensing system in the 11.8 and 2018.1 releases, we changed how licenses are authenticated. The new licensing system relies on a few additional system requirements, including a number of websites that are used during licensing and require access through your network firewall.


What's causing this?

The new licensing system uses a TLS connection with, which is secured with an Amazon-issued TLS/SSL certificate. Alteryx is packaged with a copy of the Amazon certificate. The problem arises when the network has implemented Deep Packet Inspection on TLS/SSL connections, which is a security measure requiring that a network device be able to intercept the connection and “see” the plaintext conversation. To do this, the device attempts to impersonate but uses its own certificate, which is separately installed as a trusted root certificate on the client computer. However, Alteryx doesn't consult the local computer's trust store when authenticating the license connection. Thus, when Alteryx attempts to construct a TLS session, it sees a certificate mismatch, and the connection fails.


The "quick-fix"

Since this is a network security restriction, you should have no problem activating if you move onto an external network such as a mobile hotspot, home network connection, or coffee shop.




How to confirm the problem


To definitively confirm that they are running into this issue, have them open a browser and go to
It will show a blank screen, but up in the corner is certificate information. Click on the lock to view the certificate details.









This window needs to show this exact certification Path. If there are any extra or different entries, that's when this issue occurs.


How to fix it?


IT or your security department need to add a bypass on the SSL packet inspector such that is not subject to SSL deep packet inspection. After adding the bypass so this traffic is no longer being interdicted, the issue should be resolved and the customer should try to activate again.

Thank you for sharing this.

I'm having this exact issue, so I'm glad to have found this article.


It's unlikely that I can convince our IT department to make this change.  Firewall / proxy are managed centrally, and we are a rather large company, so I doubt I can get this exception easily implemented -- my first challenge would be to find right person in IT who could address this issue and actually modify the rules.


From the description of the problem, may I ask why "the device ... impersonates" and "does not consult the local computer's trust store"?  This seems to be contradictory with how certificate authentication is intended to work.


Yes, the "fix" is simple -- get out of the office to activate the Alteryx license.  In my opinion, this "fix" is not an "enterprise" level solution.

We had this exact problem, solution was to use the 'upload activation request' method for registering the tool. As we only have a few users this wasn't too painful, but agree not an enterprise option to register each time.

Thanks for the feedback @brucedataguy and @戴卫!


I have a quick update about this issue:

Our development team has been working to resolve these issues, and as of Alteryx version 2018.1.4 (released early April) this is resolved for certificates that are not being passed through a proxy.

We're adding the proxy-support side of this to our upcoming 2018.2 release, so please stay tuned!

Since we use proxy to connect to internet, 2018.1.4 did not solve the issue, so I'm looking forward to 2018.2 to avoid others who are likely to experience this activation error when upgrading from Version 11.7 (which is what happened to me).

8 - Asteroid

I also now learned that my license key for 11.7 will not work for 2018.1.x, and a new key is to be issued to me for use when upgrading to 2018.1.x.  So I am hitting multiple challenges in my scenario -- wrong key format (11.7 --> 2018.1.x) and proxy/deep packet inspection situation due to new license activation method starting with 11.8.

I am trying to fix the same problem with Alteryx 2019.3.2.15763. We have a lot of licenses an it is impossible one by one.


Could you help me?


In general, please see the documentation to Troubleshoot Activation Issues 


Note: I have seen some cases where the command-line method of activation was successful after getting the "Your computer is unable to access the activation service." message.

I am receiving the same error for 2018.1.


I have a 2018.1 designer installed as admin, and a 2020.4 designer installed as non-admin. One day I attempted to start up the 2018.1 designer as an admin, but now I receive this error whenever I try to open either program.


Can you help me as well?




This error message indicates that the machine is having issues  connecting to the Alteryx activation service. This is typically due to the firewall/proxy on the machine or could be because there is now a corporate firewall rule preventing access to the Alteryx license servers.


Please follow these instructions. You may have to contact your organization's IT department for assistance.

  1. Make sure that Port 80 or Port 443 is open.
  2. The System Requirements of the licensing system require access to Please make sure that your organization's network has not blocked communication to this endpoint.
  3. If your organization uses a proxy, be aware that the activation request packets are encrypted and might be being blocked.

Alternatively, you can do an offline activation with a license file. Follow the instructions at Activate License Offline.
