Sandbox Merchant Activation Error

While the sandbox registration is now fixed compared to my past post, the activation url gives this error on multiple browsers. 

{"response":{"rmsg":"Internal server Error"}}

If the sandbox registration completes successfully but the activation URL returns {"response":{"rmsg":"Internal server Error"}}, the issue is likely on the service provider's side rather than with your browser or local setup.

A few things to check:

Confirm the activation link is the latest one generated for your account.
Try generating a new activation link if possible.
Check whether the sandbox environment is experiencing a temporary outage.
Contact support and provide the exact error message, activation URL (if appropriate), and the time the error occurred.

Since the error appears across multiple browsers, it points to a backend activation issue rather than a client-side problem.

If the registration is working but the activation URL still fails, it sounds like an issue on the sandbox service rather than your browser. I'd report the exact error message, the activation URL (if it doesn't contain sensitive data), and the time it occurred so the support team can check the backend logs.

Thank you. I believe that the issue stems from their sandbox merchant service that is now offline
