Here you will find the solutions for all the error messages you get when you want to debug in the server container after you have configured server side your tags and triggers.
Error Message: You cannot preview this container
When you click preview mode in the server container you might encounter the error that you cannot preview this container.
You can resolve this error by going to "Edit Container Settings". Under "Server container URLs" , add your subdomain including https://. Once you have done this you can start using preview mode.
Error Message: This site can’t provide a secure connection
If you encounter the message "This site can't provide a secure connection" it probably means that DNS has not been validated within TAGGRS as shown in the picture below. So make sure your DNS is validated.
Error Message: 404 error in preview mode
When testing a page in the preview mode of the server container you receive a 404 error.
Solution: Within the container settings, your current domain is listed. Here, the subdomain of TAGGRS should be specified; otherwise, you may encounter a 404 error.
Error Message: There is no summary for Requests
When you get the message Error Message: There is no summary for Requests when opening the server container it probably means that the data is not coming in to the server container. The cause of this is probably that there is another GTM script (hardcoded or by plugin) on the website hijacking this requests which causes the request not to come in. You need to remove this script and then most likely the data will come in to the server container.
