Create server in pgAdmin

Dear Sir/Madam

I want to create a server in pgAdmin based on the tutorial in https://dataport.pecanstreet.org/tutorial.

I filled in all parts according to the tutorial, but I face an error “auth failed”.

I have to mention that I can not find https://dataport.pecanstreet.org/access to get the username and password from there. Then I used the username and password that are used in the tutorial.

Can you please guide me on how to solve this error?

Best regards
