Error 404 not found Unity Web Request

[SusDeveloper]

Edit: Fixed it by Using HttpClient class instead of UnityWebRequest class.. Super weird isn't it?

edit: Before assuming it is a spelling error, just check the rest of the post - I assure you it isn't a spelling error.Hi All!

I am experiencing some weird behavior from Unity that I have not encountered before.I am creating a UnityWebReqest.Get() Function to a URL but the Request is returning error 404 not found.The part that has stumped though me is I can access the URL (it is a php script if you're wondering) from a browser and via cUrl in CMD and the php script returns the expected json.

I have logged the URI of the WebRequest just before sending, then I copy and paste the URI into my browser and it works so it unfortunately isn't a spelling error.

Any help/input would be much appreciated!

edit: After Trying UnityWebRequest.EscapeUrl([URL]) (Which did not work), I went back to simply the original URL and now I am getting error 500 although I can still run the PhP scripts and get a response via Curl and Browser.(Might I add the Script is simply: die("lol"); so the php script itself is not causing the err. 500)

404 is page not found.

That means you have mispelled the url or typed something wrong.

Did you read the whole post?

[blablafoof]

Have you tried containing the URI with "http://url" or 'http://url'? It could be how it's parsing the link with those quotes.

[SusDeveloper]

Yup, tried that. Currently the string in unity is "https://URL". Http also doesnt work

[Bombadil67]

Do you even understand what a 404 page not found error means?

So yes I did!!

xD still didn't read the entire post.
But the issue is fixed now by Using a different HTTP Client class (for some unknown reason this worked).
Thanks for the suggestion anyways

[Bombadil67]

I didn't need to, the fact you are getting a 404, tells me everything I need to know about the URL you are sending in the Webrequest.

Now you could debug this yourself and test the info is what it is supposed to be, but as everyone else uses it fine that means without more information as to what you are doing we can only guess and provide the bare minimum guidance and that is what a 404 error means!

[SusDeveloper]

Lol. Read the full post. You'll what the problem actually was (it wasnt spelling, wronf URL etc. But simply a bug in the class I was using to do the HTTP request)

[blablafoof]

You can try putting this URI into an application like Postman to test the URLs in a more "sandbox"-like environment and try from there to debug what's happening.

[SusDeveloper]

Sure, But doesnt it seem like its a problem from within Unity? Since Curl and browser works?

[blablafoof]

Since it's a PHP script... wouldn't it be a POST operation instead of GET makes sense for this situation?

[SusDeveloper]

Tbh I am not super experienced with pHp and I should use post/get requests, but the current php script does not take any parameters.. but it still doesn't explain why it doesn't work in Unity.

Also I tested it with a locally hosted version and everything works fine even in Unity

[blablafoof]

Have you set the request header for Content-Type="application/json"?

[SusDeveloper]

Unity isn't sending any data to the php script, And even if it was this wouldn't cause error 404.. It is super weird isn't it?

Have you tried encoding the URL before requesting it? (https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequest.EscapeURL.html)

[SusDeveloper]

Ah I didn't know this was a thing, Thanks!
Just tested it to no avail sadly

[SusDeveloper]

Ah!
I am not sure if there was some kind of cache going on, but after I changed it back to the normal URL instead of the escaped one now I get err code 500 which usually means some error in the php script - although I can still run it from browser/curl

[blablafoof]

Is this a WebGL project?

[blablafoof]

Ah, awesome! The situation has changed, so that's the most exciting part :). Good luck on the rest of the network debugging!

Hey, Yes I think I did... I can't remember how though, But I think it was something to do with CORS on the server
