PVE gui not reachable through second ip address

[AmateurProgrammer]

I have a setup with multiple vlan based sdn networks. I have assigned an ip (10.10.1.10) address for the host from management vlan. After I added ip for the host from another sdn vlan (ip 10.10.20.2), the web ui is not reachable from the newly added ip address. I can ping the host though, so some network activity does work with the host using that second ip address. @shanreich

Below are the /etc/network/interfaces file additions:

iface Mana
        address 10.10.1.10/24
        gateway 10.10.1.1

iface Storage
        address 10.10.10.2/24

iface Metsank2
        address 10.10.20.2/24

This kind of configuration used to work some time ago but I believe after some update this might have stopped working.

I'm not aware of any configuration changes that could have had impact on network connectivity for the host.

Please post the complete file. (You don't use bridges???)

From that incomplete snippet there is not reason why it should not work.

On my systems "pveproxy:8006" listens on all interfaces which have an IP address - and it replies to requests.

You might add the output of ip add show, ip route show, ss -tlpn and other helpful information...
