PowerAutomate Connector - Failed to authenticate

[suhong73]

I am trying to run my flow in Powerautomate at Alteryx. 

result : shows message that "Failed to authenticate"       

from Power Automate Configuration, I can see list of my flows and I just chose 1 (not automated flow = instant one) 

This flow does not require any input in parameter. 

 my Alteryx Designer Desktop version = 23.1 (2023.1.1.281)

 Power Automate Connector version = 1.0.1 

for your information  I am also using Sharepoint input/output connector --> this one is working fine. 

(only difference between Sharepoint & Powerautomate is "Connection Manager") 

Please can anyone help?  thankyou in advance!
