linux – vlan does not allow vm access to the Internet for what reason I don’t understand

there is a proxmox with two network devices, one is configured in an open subnet with Internet access, and the second has three vlans and a bridge on each vlan, they do not have IP addresses, then I assigned two network devices to the vm and brought them to each network via a bridge (since there are two different networks) after I started pinging the network, but there are no pings, only the error no host route comes out.Port 22 is open.
192.168.0 opened network
10.208.1 closed network
Unfortunately, I am very far from all this, so I will provide information on your questions.
