Worker not working

[almeidamarcell]

Hi,

I followed every step on the website but the worker is not working. I wanna add a subdomain. Below is the error I'm receiving and the code I used.

I am having the same issue @almeidamarcell

Hi @almeidamarcell, the 301 status code should be normal if you are trying to see it directly from the Workers Editor.

Assuming that you can't access your page vagas.cursospm3.com.br directly from the browser, check if your subdomain listed in your DNS. If it isn't, then add an A Record for vagas pointing to your server's IP address or any IP like 1.1.1.1. It should look like this:

Avise-se me saber se funciona, Javier

[almeidamarcell]

It worked perfectly! Thank you so much

It looks like 1.1.1.1 doesn't work any more: https://github.com/stephenou/fruitionsite/issues/78

Hey, @jean. Three important things to check when setting your site up:

1. Your domain/subdomain in the worker script (that should be ok if you copied the script directly from the tutorial).
2. Worker's route (step 3.5 of the tutorial). If that's already checked and you're using a subdomain, try adding an asterisk at the beggining of the route, i.e.: *subdomain.example.com/*
3. Check the A Record for your subdomain as I suggested before.

I suspect that your issue might be in your Worker's route.

[jean]

I suspect that your issue might be in your Worker's route.

You're correct, my route started with .domain instead of domain -- this is what caused the error.
