Não consigo importa tabela do endereço: https://unafiscosaude.org.br/site/campanha-de-adesao-2019/

Busquei outro endereço que tenha tabela, pois o que o professor usou não havia mais. Então usei o endereço https://unafiscosaude.org.br/site/campanha-de-adesao-2019/ no código da aula, como mostrado abaixo:

df_html = pd.read_html('https://unafiscosaude.org.br/site/campanha-de-adesao-2019/')
df_html

Mas apresentou o seguinte erro:
