Interface unreachable

Hi,
I messed up my interface. After fiddling around (with certificates, but also opnsense) I found the gui unreachable: The connection has timed out
Console is available. I did some found checks, mostly my conclusion is: Console says all is ok.

Checked port availability, if certificates are available, http, ip binds, network card name change. All seems to be in order. Reboot does not help.


I there some way I can reset teh interface without having to re-install, as I'm so happy how my VM's are running (which they still are).
 
You can edit your "/etc/network/interfaces", "/etc/hosts" and "/etc/resolv.conf". Example for a default "/etc/network/interfaces" you will find here:
https://pve.proxmox.com/wiki/Network_Configuration#_default_configuration_using_a_bridge

To create a new certificate you can run pvecm updatecerts --force

set the interfaces back to default (removing the WAN interface). I don't see anything wrong with /etc/resolv.conf. or the host file.
Any other suggestions?

Hosts:

GNU nano 5.4 /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.178.211 pve.xxxxx.xxx

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
 
I was able to fix it.
Could you access the /etc/pve/node/yourserver folder and tell what files you have there?

Can you check if the certificate pveproxy-ssl.pem and pveproxy-ssl.key match?
You can do it through the following website: https://www.dondominio.com/en/products/ssl/tools/ssl-checker/

If these two do not match, that is the problem.

You would have to generate a new certificate through the following command: pvecm updatecerts --force
Tnx, I did this before, but now I actual deleted the files first. now I can reach the page again.

It is going wrong when adding my personal certificate. It either crashes using the cabundle, or shows the wrong expiry.
But thanks for this hint. I can now play around
