I have migrated form 19.07.8 to 21.02.0 on my Archer C7.
After that a tried:
root@Repeater_WZ:~# uci set uhttpd.main.redirect_https=1
root@Repeater_WZ:~# uci commit uhttpd
root@Repeater_WZ:~# /etc/init.d/uhttpd restart
4+0 records in
4+0 records out
But nevertheless access to my router via https does not work.
I get only "Fehler: Verbindung fehlgeschlagen"
Access via http is still possible !!
Any ideas ?
