Error when connecting Jirra MCP to Claude

[John Ryan]

When attempting to connect the Jirra MCP to Claude, after Accepting receive an error screen that something went wrong

@John Ryan This error often happens when the OAuth callback between Claude and Atlassian MCP fails—usually due to a mismatch in redirect URI, missing whitelist configuration, or session expiration. Make sure your domain is whitelisted for MCP, you're using the correct callback URL, and nothing is blocked by browser or network settings. If it persists, raising a support request (link on the error screen) is the next best step.
