I try to use Umbraco Forms. It all works perfectly, including sending an email with all of its content. However, using the "Go to page" function does not work.

Independent from which Form I use, on which page I place it on and to which page I redirect to, I just stays on the form page and throws an error.

The Umbraco log function tells me that the error is:

An unhandled exception occurred

System.ObjectDisposedException: The CancellationTokenSource has been disposed.

The entire error stack is the following:

System.ObjectDisposedException: The CancellationTokenSource has been disposed.

Interestingly, this only happens on production and cannot be reproduced in our testing environment, where everything works fine.

Is there anybody who has come across something similar?
