bug: Unable to use MCP server becuase Jan does not recognize Root CA

[tuaris]

Version:
v0.7.7

Describe the Bug

Despite going through all the workarounds, it seems Jan refuses to recognize TLS certificates signed by my CA. The alternative is to connect using plain text HTTP, but then my communications will not be secure. Also, some servers will redirect to HTTPS, thus making it an impossible option.

{
  "active": false,
  "args": [],
  "command": "",
  "env": {},
  "headers": {
    "Authorization": "Basic xxxREDACTEDxxx"
  },
  "timeout": 90,
  "type": "http",
  "url": "https://jenkins.morante.com/mcp-server/mcp"
}

Steps to Reproduce

1. Setup and MCP server using HTTP of SSE
2. Attempt to connect to it
3. Observe error in log
