If port 80 is not used anywhere by the Mender server, I would like to close port 80 on our reverse proxy. Are 443 and 9000 the only ports required by the Mender server to support devices? ---

Hi @jmeirow I do not believe port 80 is needed. @tranchitella can you confirm? Please report any issues you see after closing it. Drew ---

@jmeirow I confirm in a default installation, the Mender backend doesn’t need port 80 open. ---
