The Facebbok Lead Ads Tool stopped working 2 days ago for me.
I now get this in the console log: Failed to load https://www.facebook.com/tools/lead-ads-testing/form-validation/?dpr=2&__a=1: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://developers.facebook.com' is therefore not allowed access. The response had HTTP status code 404.
Anyone else having this issue? Is there any work around? I have tried all browsers.

I am using next.js and I need to send an AJAX request (I am using isomorphic-unfetch). Some cases the response is with 302 HTTP status code and I need to redirect to the URL that comes in response. For redirecting, I have tried with Router.push(url) and window.location.href=url due is a client redirection.
The problem is that in IE11 appears the error (other browsers works well)
The redirection is done but it takes about 10 seconds. I was googling and found this SCRIPT7002: XMLHttpRequest: Network Error 0x2ef3, Could not complete the operation due to error 00002ef3 that describe a bit my problem but none of the proposed solutions fixed my problem.
Other posts suggest changing the status response but I have no control to the requested endpoint so I can't change anything.
Any ideas on how to solve this?
I recently hosted a website on AWS S3 as a static page. For some unknown, Facebook won't allow me to submit the app using https://www.spotin.io/privacy-policy as an url because of a bad response code.
For now, I just added a simple generic privacy policy until I fix this, but I really need help. I read the other questions in Stack Over flow but their from 2 years ago and I following the given advice but it didn't work.
Here I include Facebook's debugger response image:
Facebook Debugger
Can someone help please?
You seem to use CloudFront. Your page already delivers 404 code as a response:
via https://httpstatus.io/
via Postman
Check your CloudFront setup, especially the Errors section. This alternative question might be of help:
CloudFront got X-Cache: Error from cloudfront with Status Code 200
I want to publish my first Facebook application and a Privacy Policy URL is required.
I have the page privacypolicy.html published in my website but I get the next message when I configure it in "App Details":
You must submit a valid Privacy Policy URL in order to be compliant with Facebook Platform. Request failed with error:
Bad Response Code: URL returned a bad HTTP response code.
The http code returned when I request the page is 200
Any ideas?
The URL is cached by facebook.
Adding # at the end of my Url did the job ..
This is an old question I know, but I figured I'd post my solution and hope it helps anyone. For me I got this error because I had rewrite rules that didn't catch the URL that Facebook actually goes to in order to get the privacy policy. Facebook adds a query string to the URL that you give it for the privacy policy and since my privacy policy page doesn't do anything with the query string, I didn't check for it in my rewrite rule.
You can check out how Facebook scrapes the page you give it by going to Facebook's Sharing Debugger and putting your URL in the input bar. You can also see the last time that Facebook tried to scrape that URL and tell Facebook to try again once you've fixed any issues. This will get around the caching that was mentioned in user2390340's post.
Facebook externalhit appears to request via the ipv6 address published in DNS if there is one available and won't check on the ipv4 published in DNS.
If your website doesn't have ipv6 enabled it'll return a 404 or 500 and you'll get that error "Bad Response Code: URL returned a bad HTTP response code" for your Privacy Policy URL.
Edit:
Also noted that Facebook caches the URL, I was checking it and getting a "bad response code" error even though there was no hit from their UA in the access logs.
Adding ?stuff onto the end of the URL in the Privacy Policy field bypassed a cache and the access log hits showed up with 200 OK, allowing the URL to be saved.
Not sure if this is related to user2259887's comment about Facebook using IPV6 DNS. But after reading his comment, I was able to work around the validation issue by specifying an IP Address URL instead of using the host domain name URL.
This workaround will not work well if the site IP address is dynamic or change often.
i've read all the other questions about this subject and so far i can't figure out what's the problem.
The website is http://bowarrow.de and it works fine. Only Facebook has a 403 problem. I added meta tags and i find them in the source code.
Still "Bad Response Code: URL returned a bad HTTP response code." if i enter it here https://developers.facebook.com/tools/debug
I contacted my hoster to ask if it is a mod_security error but they said there is no mod_security on my account.
I use hostgator as a host and host europe for my domain.
I see that this question has been asked before but no solution has been provided.
I am getting nothing but 500 Internal Server Error since yesterday when I use following link:
http://apps.facebook.com/myappID
Yes, I already tried clearing up my cache & cookies so don't even bother asking me this. I have added my app link in the Canvas URL which should show up after I click on the app URL but nothing but that 500 HTTP error. I tried on all browsers and even asked few of my friends too and they said same error.
I thought it was an error on Facebook but I don't see how it's not being fixed for a day now.
Any help? Thank you.
The 500 Internal Server Error is a very general HTTP status code that means something has gone wrong on the web site's server but the server could not be more specific on what the exact problem is.
So its a "server-side" error, meaning the problem is not with your PC or Internet connection but instead is a problem with the web site's server.
Maybe you should contact facebook help center.
I just ran into a similar situation and found that when I reduced the limit in my GET call to 20 rather than 500 the server responded well.
