[Credentials denied] Tableau Output tool in Alteryx Designer

[VINICIUSRR]

Hi!

From a few weeks ago I have tried to connect Tableau Server with output tool, but it always shows Credentials denied (error code 406) message.
Also, I also tried using the previous output connector (Publish to Tableau Server Tool) which was working normally. However it is also giving the 406 error.

The same message also appears for the tool Tableau Input. 

Can anyone help with solving this problem?
