Salesforce - Unable to connect
It turns out the problem was due to TLS settings for Internet Explorer/Internet settings in Control Panel which had been turned off. Now that they are checked, everything is good.
The following alternative solution worked for me, to fix the issue for both Excel and PowerBI. I added two entries into the registry:
Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
Right click --> Select 'New' --> DWORD
Enter 'Excel.exe' as value name
Right click on the new entry --> Select ‘Modify…’
Enter '2af9' as value data (hex)
Right click --> Select 'New' --> DWORD
Enter 'PBIDesktop.exe' as value name
Right click on the new entry --> Select ‘Modify…’
Enter '2af9' as value data (hex).
Others have reported that 2af8 worked for them, but it didn't for me.
