Erro err_cert_authority_invalid com certificado Comodo SSL e Positive SSL

Como instalar certicado comodo ssl, positive ssl
Como instalar certicado comodo ssl, positive ssl

Sempre comprei certificados da Comodo (Comodo SSL e Positive SSL) para utilizar em lojas que administro e ontem me deparei com uma situação estranha, instalei o certificado e estava acessando normalmente nos meus computadores (desktop e tablet), porém ao acessar pelo Chrome no celular me deparei com o erro “err_cert_authority_invalid“, testei de diversos dispositivos versão mobile e o erro aparecia em todos, veja a solução que encontrei:

Você recebeu da Comodo, os arquivos compactados:

  1. AddTrustExternalCARoot.crt
  2. COMODORSAAddTrustCA.crt
  3. COMODORSADomainValidationSecureServerCA.crt
  4. seu_dominio_com_br.crt (seu certificado)

Os 3 primeiros arquivos (AddTrustExternalCARoot.crt, COMODORSAAddTrustCA.crt e COMODORSADomainValidationSecureServerCA.crt) precisam ser “juntados“, para isso abra os 3 arquivos no bloco de notas, notepad++ ou qualquer outro editor de texto simples, copie todo o conteúdo e cole em um novo arquivo (na sequência), vai ficar assim:
