Since today, the Atlassian MCP integration stopped working unexpectedly during an active chat session.
When I try to authorize the app, the OAuth page shows:
“Atlassian MCP is requesting access to your Atlassian account.”
After that, the progress ring keeps spinning indefinitely and the flow never completes.
The authorization fails in Claude Desktop with the message:
“Authorization with the MCP server failed. You can check your credentials and permissions. If this persists, share this reference with support: ofid_9ba90d073f455a49”
I already tried:
reconnecting the integration,
removing and re-adding the connection,
restarting Claude Desktop multiple times,
testing in the browser,
deleting the browser cache in Chrome,
trying again with Microsoft Edge.
None of that fixed the issue.
The interesting part is that it still works in Claude CLI, but not in the browser/desktop flow. That makes it look like an OAuth redirect or session issue specific to the desktop/browser authorization path.
Expected behavior
The Atlassian OAuth consent flow should complete successfully and return me to the app with a working MCP connection.
Actual behavior
The consent screen stays stuck loading forever and the authorization never completes.
Environment
Claude Desktop on Windows
Atlassian MCP endpoint: <a href="https://mcp.atlassian.com/v1/mcp" rel="noopener nofollow noreferrer" target="_blank">mcp.atlassian.com/v1/mcp</a>
