Custom domain don't work

[phosec]

While setting up a self hosted version of interactsh-web I get this error while registering my custom domain :

index.js:1 Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.
    at CustomHost

The POST call to /register is successful tho,

The version hosted at https://app.interactsh.com/ does not work either with my custom domain,

The cli client works fine

Any idea ?

Thanks
