// opening the base URL
driver1.get(baseUrl+"/");
// opening a new tab
driver1.findElement(By.cssSelector("Body")).sendKeys(Keys.COMMAND + "t");
driver1.get("my URL");
// getting back to the first tab
driver1.findElement(By.cssSelector("body")).sendKeys(Keys.COMMAND, Keys.SHIFT, "{");
// I want to signup by clicking the sign up button
driver1.findElement(By.xpath("/html/body/div[1]/header/div[2]/button")).click();
The error that I get after running is : "Error communicating with the remote browser. It may have died."
But when I run the same code without the navigation, the button click works fine, then it means there is no problem with the xpath.
