"Failed to add connector link" Error for Custom Connector with No Authentication

Issue Summary

We have published a custom connector (e.g., “openai-mcp-external”) to our workspace using remote MCP with no authentication. The connector works as expected for the user who created it. However, other organization members—including admins—receive the following error when attempting to connect:

“Failed to add connector link”

There is no additional error information provided.

Steps to Reproduce:

  1. Add and publish a custom connector with no authentication to the workspace.
  2. Another user attempts to connect via the workspace.
  3. User receives a “Failed to add connector link” error.

Request: We would appreciate any guidance or recommendations on how to make the connector accessible to other organization members.

We’ve actually figured out the solution: users need to click on their user icon (bottom left corner) → settings → connectors → choose the needed connector → and then click “Connect”. This information wasn’t clear from the error message “Failed to add connector link” or the documentation.

Thanks for sharing! I’d add that even after doing this, you still need to hard refresh the chat interface for it to take effect the first time.

We just started getting this error on our existing internal connector. People how try to connect the first time (or after disconnecting) get this error message. The network tab has a failure here - it looks like something is wrong with this internal call? POST https://chatgpt.com/backend-api/aip/connectors/links/oauth 404 (Not Found)

Hi @Ryan_Rosztoczy, that 404 on the connector link call does look like something the team will need to inspect from the backend side, especially since it affects first-time connects and reconnects.

Could you kindly create a support ticket at support@openai.com, then drop the case ID here? That’ll make it easier for the team to monitor this thread and troubleshoot against the right connector/account details.
