After rebooting core instances or changing core configuration, all gateways will be disconnected / getting errors until restart:
defguard_gateway::gateway: message=Failed to retrieve WireGuard interface statistics: Netlink error: Netlink payload error: No such device (os error 19) log.target=defguard_gateway::gateway log.module_path=defguard_gateway::gateway log.file=src/gateway.rs log.line=618 [2.0.2 Debian 13.0.0 x86_64]
Before that happens, we get these logs:

This applies for gateways and also proxies.
We also have some gateways with added cache space, same problem.
Could you please find a solution for that or is it fixable?
