+**Source**
+Upstream openclaw/openclaw commit `8790c54635`
+
+**Why**
+Gateway setup URLs or explicit manual endpoint inputs shouldn't enforce default ports blindly when displaying the connection UI or verifying connection security, particularly ensuring custom or cleartext implicit ports accurately reflect their configuration.
+
+**Adaptation**
+Ported the modified `displayUrl` string building logic from `GatewayConfigResolver.kt` (upstream) to `GatewayConfigUtils.kt` (this repo). Added tests covering various edge cases (bare domains vs default ports).
+Modified test parameters in `GatewayConfigUtilsTest` to use local `192.168.1.100` instead of `gateway.example` for cleartext, as `NetworkUtils.isUrlSecure` in this repo explicitly forbids public domains for WS/HTTP connections.
+
+**Excluded upstream behavior**
+N/A. This was a direct logic porting.
+
+**Verification**
+Locally verified by running `./gradlew app:testStandardDebugUnitTest app:lintStandardDebug` ensuring all updated assertions succeed and no memory or regressions are flagged.
