      Current configuration looks like this:

      I tried applying the settings as reported in your last message, but still have trouble redirecting to https://nextcloud.projectus.com

        The settings in my message are exactly what you posted just to ask confirmation if that is what you currently had active. The settings are wrong indeed.

        Try making them like this:

        	use_backend HA_Sistemas-45-14_80-www_ipvANY  if  !time-sheet !qsms !treinamento !proposta !chamado !pesquisa !pesquisa-ce !nxc
	use_backend HA_Sistemas_40-245_443-nxc_ipvANY  if nxc 
	default_backend HA_Sistemas_43-235_8443_ipvANY

          @PiBa I set up according to your last message, but the problem persists, continuing to direct nextcloud.projectus.com.br to the main site of the company.

            Seems to me that https://nextcloud.projectus.com.br/ is working just fine..? Can you confirm that?

            Perhaps you have another frontend that is listening on :80 that is sending a wrong redirect?

              @PiBa redirection occurs, but leading to the wrong page, I have another frontend that responds to requests on port: 80.

                @PiBa can you explain to me, why the backen only focused up after using the setting "HTTP / 1.1 \ r \ nHost: \ nextcloud.projectus.com.br"?

                  Can you tell me why your nginx configuration requires the host header to be send in requests?

                    @PiBa I really don't know why ngix requires the header to be sent on requests; I followed an Internet totorial to deploy "nextcloud" using nginx. Can you open the link to try to help me understand?

                      @PiBa Hi man, these were the answers I found about your question.

                      In order to figure out which virtual host to use, I think

                      This causes you to go to the default_server host_server

                        Then it seems you have answered your question why the host header must be send in checks 👍 . HAProxy's health-checks by default do not send this header and your nginx configuration needs it to find the correct virtual host with the server_name configuration. The 'default virtual host' likely returns the 400 response status. Its nice to know that doing some research and actually understanding how things work you can succeed with fishing without needing other people to give you the fish, that will definitely help with future diagnosing of issues.
