“connection cache” when accessing Sharepoint

I need to get data from a sharepoint list.

The first time I enter the URL the connection succeeds and I’m being prompted with several login options. but I probably chose the wrong one because I got an error message (HTTP 404).

The real issue is that I can’t get through that process again.

It is as if PBI had cached some of the connection information and went straight away to connecting with my last (and only…) connection method.

I got a colleague to try it out – the first time it connects and he is presented with login options. Login fails. From then on he also gets a 404 error right away and is never presented with the possibility to try other login options.

Does that ring a bell to anyone?

How we can we clear the “connection cache”?

Thanks!
