Can't connect to HA after disabling IPv6

Configuration
1

Hi there!

I can’t reach HA. Long story short: I went into “Supervisor → System” and I disabled IPv6, since I’m on a IPv4 network. Now I can’t access HA. Samba is not working either.

I guess I need to access the SD card, right?

Any suggestions? Thanks!

[SOLVED]

Just in case anyone struggles with this: I connected a keyboard/screen and turned on IPv6 using CLI.
