After navigating to localhost my chrome console shows some error:
ERROR Error: Uncaught (in promise): Error: Contract has not been deployed to detected network (network/artifact mismatch) Error: Contract has not been deployed to detected network (network/artifact mismatch) at contract.js:419 at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invoke (zone.js:391) at Object.onInvoke (core.es5.js:3890) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invoke (zone.js:390) at Zone.webpackJsonp.../../../../zone.js/dist/zone.js.Zone.run (zone.js:150) at zone.js:889 at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:423) at Object.onInvokeTask (core.es5.js:3881) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:422) at Zone.webpackJsonp.../../../../zone.js/dist/zone.js.Zone.runTask (zone.js:195) at resolvePromise (zone.js:831) at resolvePromise (zone.js:788) at zone.js:892 at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:423) at Object.onInvokeTask (core.es5.js:3881) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:422) at Zone.webpackJsonp.../../../../zone.js/dist/zone.js.Zone.runTask (zone.js:195) at drainMicroTaskQueue (zone.js:601) at ZoneTask.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneTask.invokeTask [as invoke] (zone.js:502) at invokeTask (zone.js:1744)

Am I not able to login because of this error?
