Hi Team,

I am using “WebUI.authenticate” to authenticate my application.

It gives me this error:

Unable to navigate to authenticated page (Root cause: org.openqa.selenium.WebDriverException: unknown error: unhandled inspector error: {“code”:-32000,“message”:“Cannot navigate to invalid URL”}

URL I am trying to access is: [http://optimuscf.staticso2.com/PAMP1111](http://optimuscf.staticso2.com/PAMP1111)

Sorry but I can not disclose the password, just to let you know that my password contains “@” symbol, is it causing the problem?

Please suggest.

Hi Jagjeet,

Yes, I think there may be a problem when you use (at) sign - I don’t know how Katalon uses it internally, but generally, Basic auth can be performed as **[https://username:password@yoursite.com](https://username:password@yoursite.com)** and your (at) sign may make a mess.

Try to use HEX representation of (at) which is **%40** - so if your password is “myP@ssword”, rather use “myP%40ssword”

Once I have ever tried `WebUI.authenticate()` and found it does not work.

I’ve tested using format

```auto
WebUI.navigateToUrl('http://user:pass@host')

```

and it works.
