Click in selenium python doesnt works

Question

I have tried clicks with the id, css selector, tag name, link name, xpath, etc. But does not works.

This is the HTML:

<a id="download" class="small-button smallred" data-url="//file-converter-online.com/download/" style="display: inline-block;">
                                        Start Converting!                                    </a>

I am using python 3.7.1, webdriver (chrome), selenium module. How can I solve this?

My failed attempts:

browser.find_element_by_id("download").click()
browser.find_element_by_xpath('//*[@id="download"]').click()
browser.find_element_by_css_selector(".small-button.smallred").click()

ERROR
