Unable to show pictures with "Image role" or Image objects on dashboards due to TLS 1.3

問題

When trying to show pictures with "Image role" or image objects on dashboards, they are not shown but the web page object on Google Chrome for example, can show the image from the same HTTPS URL.

環境

Tableau Desktop
Image role
Image objects

解決方法

Change the web server to support HTTPS with TLS v1.2.
Upload the same image to another web server that supports TLS v1.2.
Use HTTP instead of HTTPS if possible.

Vote on the Tableau Community Idea to Allow Tableau products to utilize TLS 1.3.

原因

The web server delivering the images does not accept anything other than TLS v1.3. Desktop currently supports TLS v1.2.

其他資訊

You can check the supported TLS version with the following curl commands.

curl -v -s --tlsv1.2 --tls-max 1.2  https://example.com/sample.jpg --output /dev/null
curl -v -s --tlsv1.3 --tls-max 1.3  https://example.com/sample.jpg --output /dev/null
