Hi, CL
That message usually means the Stocks data service in Excel is having a temporary problem on Microsoft’s side, so it may not be your file or PC. Here are some suggestions you can try:
First, wait a bit and try Data > Refresh All again. If it still fails, close Excel fully and reopen the workbook. It is also recommended that you check File > Account and make sure Excel is signed in with the Microsoft 365 account tied to your subscription, then run Update Now in case the app is behind.
If it still will not refresh, try opening the same file in Excel for the web. Sometimes linked data types behave better there. If the pop-up keeps interrupting your work, you can temporarily change that stock data type to Manual refresh so Excel stops nagging, though the values may stay old until the service is back.
Thank you for your patience in reading, I hope this information has been helpful to you.
