Status: RESOLVED DUPLICATE of bug 1748416

(Thunderbird :: Account Manager, defect)

Description

Attachment: ScreenShot 2025-01-24 16.55.05.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:134.0) Gecko/20100101 Firefox/134.0

Steps to reproduce:

I am using Mac OS 15.1.1.
I have installed Unity Accelerator for game development.
Unity Accelerator was running on port 80.

Actual results:

I installed Thunderbird and performed OAuth2 authentication for Gmail.
I entered my ID and password and performed authentication, but communication did not take place and the OAuth2 authentication window appeared again.

As you can see in the attached image, it seems that the OAuth2 authentication was trying to communicate with localhost and failing, so by changing the port used by Unity Accelerator from 80 to 18080, the OAuth2 authentication was successfully completed.

From this, it is clear that the port used by localhost for OAuth2 authentication should not be fixed at port 80, but should use an available port other than that.

Expected results:

After performing OAuth2 authentication for Gmail, the Gmail data should have been received.
