[SOLVED] pve webui and ssh not working

[Waldorf]

I did not work on my PVE for 6 months and found it with this broken webui and ssh access.
I might be the cause of this issue due to changes back in the day but I do not remember.
Anyway, the first pve7.3 install did work and since this is a clean new server I reinstalled proxmox 7.3. However, pve webui and ssh to the pve still don't work.
Trying to login to pve in a browser with '192.168.178.55:8006' I get the error: "192.168.178.55 didn’t send any data. ERR_EMPTY_RESPONSE"
SSH into 192.168.178.55:8006 I get a Putty fatal error "Remote side unexpectedly closed network connection"
A ping from pve server to e.g. google.com works, a ping from a windows command prompt to 192.168.178.55 does work. My laptop has ip 192.168.178.30

root@pve:~# cat /etc/network/interfaces
auto lo
iface io inet loopback
iface enp4s0 net manual
auto vmbr0
iface vmbr0 inet static
address 192.168.178.55/24 (the router always assigns this IP address)
gateway 192.168.178.1
bridge-ports enp4s0
bridge-stp off
bridge-fd 0

root@pve:~# ip a

inet 192.168.178.55/24 scope global vmbr0

The machine is an MSI with 8 core intel and 128G memory.

I hope I provided enough info and one of the forum members can guide me with this issue.
Thanks in advance!

You really need to use https://192.168.178.55:8006. With http it won't work.

SSH is port 22 not 8006.

net 192.168.192.55/24 scope global vmbr0

ip a tells you that 192.168.192.55 is used and not 192.168.178.55. So this doesn't match what it should be according to your shown network config.

Ok i'm a bit ashamed now
'https' is the resolution.

ssh with port 22 works too.
ip a: i made a typo in the address 192.168.178.55 is right.

thanks Dunuin
