Does Executing JRS report url from Excel Workbook has any password limitation

Hi,
I have created a JRS report and trying to execute the same from excel sheet by adding the URL in Data > From Web. When logging with my credentials it is requesting login for multiple times and also the issue is resolved after changing my password.
I want to clarify is there any password limitation like Password should not contain special characters like ! , % and so on while execute a JRS url from Excel.
