Hello Thiago, There's something wrong with the link used in Homepage under d/control, it's actually an issue on the server redirection to https. http://www.cti.gov.br/invesalius/ redirects me to https://www.cti.gov.brinvesalius/ which is invalid, it should redirect me to https://www.cti.gov.br/invesalius/ instead.
So the issue needs to be fixed in CTI's server, but you can also update the url to use https on d/control. It seems like you're the right person to report this problem to so I'm replying here. Thanks, -- Samuel Henrique <samueloph>
