Description

• Respect configured TigerGraph gsPort and restppPort during UI login

• Fix /ui/ui-login incorrectly falling back to pyTigerGraph default RESTPP port 9000

• Apply the same connection port configuration to both username/password and API-token login paths

• Prevent valid TigerGraph credentials from being rejected when TigerGraph is exposed on a non-default port such as 14240

Pass configured TigerGraph gsPort/restppPort into UI login TigerGraphConnection calls

---

Validation

• Reproduced the issue with TigerGraph exposed on port 14240

• Confirmed TigerGraphConnection(..., gsPort=14240, restppPort=14240) succeeds with the same credentials

• Confirmed the existing /ui/ui-login path fails because it falls back to port 9000

• Confirmed /ui/ui-login returns 200 OK after passing configured gsPort and restppPort

🔒 No security concerns identified

⚡ Recommended focus areas for review Default Ports Validate that passing None from db_config.get("gsPort") or db_config.get("restppPort") does not override pyTigerGraph constructor defaults when these keys are absent. If pyTigerGraph does not handle None, omit the arguments unless configured. conn = TigerGraphConnection( host=db_config["hostname"], gsPort=db_config.get("gsPort"), restppPort=db_config.get("restppPort"),
