Hello.
Write using a translator.
When you replace the extracted Data Source from Tableau Desktop or connect to the same Data Source on the Tableau Cloud, you get a photo-like error.
Help me!
Tableau Desktop에서 추출된 Data Source 바꾸기 혹은 Tableau Cloud 상에 있는 똑같은 Data Source에 연결했을때 사진과 같은 Error가 발생합니다.

The error message in the screenshot you provided is in Korean and reads:
"sqlproxy:1t0or6403eyhjyj196ujxy01cspwl에 다시 연결하시겠습니까?" This translates to: "Do you want to reconnect to sqlproxy:1t0or6403eyhjyj196ujxy01cspwl?"
This type of message usually indicates a temporary connectivity issue with the data source.
Try connecting to the same data source from a different machine or network environment to see if the issue persists. This can help determine if the problem is specific to your current environment.
