How to get around or ignore the HTTPS check in chrome

Hello,

I am looking for a way to get past or ignore the browser HTTPS check. For example

*** Settings ***
Documentation This is some basic info about the whole suite
Library SeleniumLibrary

*** Variables ***
${BROWSER} = chrome
${NAV_URL} = https://172.111.111.11
${VALIDUSER} = testuser
${VALIDPASSWORD} = password

*** Keywords ***
Navigate to URL
Open Browser ${NAV_URL} ${BROWSER}
maximize browser window
Login In

Input Text  //input[@name="j_username"]    ${VALIDUSER}
Input Text  //input[@name="j_password"]    ${VALIDPASSWORD}
click button  id = loginButtonId

I developing this automated script in which I can’t get a valid cert.

Thanks in advance
