I have a Vaadin-based web application and deployed it to my Tomcat 8 web application server. To access the application without a port number, etc., I installed the Apache web server and configured VirtualHost for the proxy server . Now the problem is that I always get the following message if I try to click on a button, etc. In a web application:
Cookies disabled This application requires cookies to function. Please enable cookies in your browser and click here or press ESC to try again.
All cookies are enabled and I am using the Chrome browser. Cookies from this web page are also retrieved and valid.
If I access the web application in the usual way using the port specification, I can click all the content without errors.
