You are not alone. We have the same problem, starting yesterday.
I am the IT support for our company, but not listed as a contact able to contact support. [Our root contact is away on vacation]
I noted in the logs the API call to update the exchange rates, and was able to isolate it to an error "Missing Password" being returned by wallst.com
For example, this URL returns the error:
http://www.quickbooks.wallst.com/api/currency.asp?User_ID=CurrencyUser&User_Tier=API&User_TimeStamp=...
This URL (with User_ID) removed, works. But this isn't how QuickBooks calls the API
http://www.quickbooks.wallst.com/api/currency.asp?User_Tier=API&User_TimeStamp=20230613125313&baseCu...
If someone is able to provide this info to Support, this can likely be fixed sooner than later.
