[Bug]: Atlassian(Rovo) MCP Server cannot auth properly for individual users

[happytreees]

What happened?

When attempting to use the Atlassian(Rovo) MCP server we are never able to authenticate, or store the oauth tokens.

After approving the oauth, and accepting via Atlassian I am redirected back to Libre and a message stating the authentication has failed.

Version Information

v0.8.3

Steps to Reproduce

Attempt to setup Atlassian MCP server in Libre

What browsers are you seeing the problem on?
