I had some issues with my Turris (unable to logon to Reforis, but could logon to Luci)& decided to do a reflash rather than mess with it further. It was set to auto-update, so should have been on 5. I reflashed to https://repo.turris.cz/hbs/medkit/omnia-medkit-latest.tar.gz dated Feb 08 2022
After re-flashing & doing a factory reset I tried to logon. The web page at the set password screen kept refreshing every 10 seconds or so. Even if I typed in a password quickly it would throw some error I couldn’t quite catch & refresh the web page again.
Moving to Chrome seemed to fix thing & I proceeded with setup. More of a bug report than request for help at this point.
