Why does Styku Studio show "Connection error: Unable to connect to the license server" after updating my account email?

After updating your account email in Styku Studio V5, a credential mismatch can occur between your account and the license server. This blocks you from logging in and using your scanner. This issue cannot be resolved on your own — Styku Support needs to fix it on the backend.

What causes this error?

When you change your account email address during the Styku Studio V5 setup or update process, your login credentials may not stay in sync with the license server. The software shows this error:

"Connection error: Unable to connect to the license server."

This is a known issue that can happen when:

• The email address on your Styku account was changed during or after the V5 Studio update
• The original email address was no longer accessible when the verification code was sent
• The new email address was accepted by the system, but the license server was not updated to match

Note: Per Styku's software license terms, you are responsible for following the recommended activation and installation procedures for the software. Failure to do so — including account changes that result in activation mismatches — constitutes a breach of the license agreement. Contact Styku Support promptly to resolve any such issues.

How to update your account email address (before this error occurs)

If you need to change the email address associated with your administrator account, follow these steps within the Styku app to minimize the risk of a credential mismatch:

1. Press Settings to open the Settings menu.
2. Scroll down and select Accounts and Privacy Controls.
3. You will be asked to log into your account. Enter your current email and password to continue. If you don't remember your password, press the Forgot Password button.
4. Choose the Administrator Account option to edit your account information. Follow the on-screen instructions to complete the update process.

Completing the update through this flow helps ensure your credentials are updated correctly across the system.

What to do if you are already seeing the error

You cannot fix this error yourself from the Styku Studio software. Contact Styku Support so they can reconcile your account on the backend.

1. Go to the Styku Business Portal at styku.com/portal and submit a support ticket using the ticket form.
2. In your message, include:
   • The original email address on your account (even if you no longer have access to it)
   • The new email address you updated to
   • The name of your business and location
   • A description of the error message you are seeing
3. A support agent will contact you to resolve the issue. Expect a response within 1 business day.

Important notes

• Styku does not have a phone support line. Calling will not reach a live agent — submit a ticket through the Business Portal to make sure your request is received and tracked.
• Response time target is 1 business day. If you do not hear back within 1 business day, resubmit your ticket through the Business Portal to escalate urgency.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: your original account email address, the new email address you changed it to, your business name, and a screenshot of the error message.
