Authentication failed for JIRA API

I have generated PAT just 2 days ago and when i connect to MCP server and try to use tool jira_get_issue, i'm always getting below auth error:

Docker-compose:

raise HTTPError("Unauthorized (401)", response=response)

The above exception was the direct cause of the following exception:

raise MCPAtlassianAuthenticationError(error_msg) from http_err
mcp_atlassian.exceptions.MCPAtlassianAuthenticationError: Authentication failed for Jira API (401). Token may be expired or invalid. Please verify credentials.

All the MCP tools are listed. But when i try accessing the tool, getting auth error.
Am I missing anything?
