Is port 80 used anywhere by Mender?

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.

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

@tranchitella - Thank you!
