Issue with Tableau 2025.3 Apple Silicon connecting to tableau server

Hello All,

I’m using Tableau Desktop 2025.3 on an Apple Silicon Mac and connecting to our Tableau Server at:

https://mytableau.nameoforg.org

Issue summary:

• I can sign in and browse workbooks on the server
• During sign-in, I see two login pages:
  1. https://fs.nameoforg.org
  2. https://mytableau.nameoforg.org
• After I select a workbook and click Open, Tableau prompts me again to connect to: 
  https://fs.nameoforg.org
• Then I get this error: 
  “Cannot connect to Tableau Server. Please check the server name and port and try again.”

Expected behavior:

• Tableau Desktop should authenticate via SSO if needed, but continue using https://mytableau.nameoforg.org as the Tableau Server
• The workbook should open without prompting me to connect to https://fs.nameoforg.org as if it were the Tableau Server

Observed behavior:

• fs.nameoforg.org appears to be treated as the Tableau Server during workbook open
• Connection fails at that step

Environment:

• Tableau Desktop: 2025.3
• Hardware: Apple Silicon Mac
• Tableau Server: https://mytableau.nameoforg.org

Repro steps:

1. Open Tableau Desktop
2. Sign in to Tableau Server at https://mytableau.nameoforg.org
3. Authenticate through the NYU login flow (https://fs.nameoforg.org)
4. Return to Tableau Server and view available workbooks
5. Select a workbook and click Open
6. Tableau prompts for server sign-in again, showing https://fs.nameoforg.org
7. Error appears: “Cannot connect to Tableau Server. Please check the server name and port and try again.”

I tried using agentforce to address this issue, and recommended using default browser to auth. I did the change and now this is the error that I'm getting:  

Unable to complete action 

Authentication failed. 

Error Code: 84223ADA 

Tableau received an OAuth error from your request.  Please see the error message for more information: Use JsonReader.setStrictness(Strictness.LENIENT) to accept malformed JSON at line 3 column 1 path $

Can't seem to get tableau to work on macOS. I can use it on a VDI on windows but I rather use my own hardware since it is faster.
