Status code 503


I do have couple of websites running in Cloudflare. Now, when I do check these websites on, I see:

Status code

Status message
Service Temporarily Unavailable

When I disable Cloudflare, all is working fine.

I talked with the hosting company (Cloudways), and they told me that there is something going on with Cloudflare and I should contact them. That’s what I am doing now.

Can someone please assist why this happening?

I can’t edit my first post.

The error status code 503 happens with both “” and “”.

This will be most likely one of the challenges. Either JavaScript or CAPTCHA. Check your firewall event log for any related entries.

What’s the domain?

The domain is REDACTED

When I look in the firewall event, I only see “bot fight mode”.

Then it will be most likely that. Try disabling it.

That worked, thanks!

Now just to understand it a bit. What is the recommend way? I thought that it’s better to enable bot fight mode in the Firewall settings.

Is it recommend to enable it and that I do get Status code 503. In the browser it’s working fine, but maybe for SEO it’s not good that I do get such error.

It depends on what you need, but with the security layer you can have such challenges and they will return a 503. The 503 itself is not the issue though.

Thank you for the help Sandro.

One other question, is your “www” record an A record or a CNAME record?

My “www” record is a CNAME record.

For others that will read this, it’s also good to know when you have “Bot fight mode” enabled, you can’t preload HSTS (

After you disable “bot fight mode”, it will work.
