Hi @gioboa
Sorry, I wasn't running the right example project for testing. Now it works fine on my computer. Can you run the checks again, please?

[nicotu01]

Hi @gioboa
All checks have passed.
Is it ok for you ?

It looks great to me, why we are doing a special check for 0.0.0.0 ?

Hi @gioboa
The Vite option server.host can be a string or boolean.
Here are the possible values :

• (by default) : it listen on localhost
• false : it listen on localhost
• true (= 0.0.0.0 ) : it listen on all addresses, including localhost in serve context
• 0.0.0.0 : it listen on all addresses, including localhost in serve context
• ${ip address} : it listen on ${ip address}

In IPv4, the address 0.0.0.0 is a non-routable meta-address used to designate an invalid, unknown, or unreachable destination.
So, it is better to configure the default routable host in this case.
