A strange issue on Dwellers with HE tunnel: connections to port 22, 80, or an arbitrary one work, but not to port 443.

We tried:

• new port on nginx: works
• explictly allows port 41: sill the same issue (well, if it works for other ports ...)
• reset iptables rules: still the same issue
• watch netstat for incoming connections: never appear
• try tunnel routing IP / routed IP: same issue

As a temporary solution, I've removed the following AAAA records to the canonical IPv6 of Dwellers:

lists.
app2.
dwellers.
social.
www3.

bugzilla.espace-win.org.

Could be worthwhile to ask HE for assistance.
