firewall issues.

Hi,
i'm trying to setup proxmox backup server firewall but i'm stuck.
i have setup the following iptables rules on the backup server
-I INPUT -s pve_ip -j ACCEPT
-I INPUT -s my_home_ip -j ACCEPT
-A INPUT -j DROP
which should accept all packets from my home and the pve server and drop all from all others.
while i'm able to ssh into the backup machine(from both my home and the pve) backups do not work and i can't login to the backup interface at https://ip:8007
note that the login screen comes but won't accept the password
when i disable the firewall everything works perfect
could you please help?

i solved it by adding:

-I INPUT -i lo – j ACCEPT
-I OUTPUT -o lo – j ACCEPT
