Could not use requested subdomain, retrying

Hi there,

I try to build an integration app.

I set my subdomain and it worked well until today.

But today I got and log
‘could not use requested subdomain, retrying’.
and generated random name.

I need static subdomain to put it in my webhook integration recipe.
Is anyone know why the used subdomain can’t use anymore?

I have no idea of ‘@mondaydotcomorg/tunnel’ so I hope someone can help me!
