Unable to find manifest HELPPLS

I’m working on digital ocean for the first time, and I swear I went over my main.py, openapi.yaml, and manifest.json files 1,000,000 times, and nothing seems wrong. However, whenever I put in the URL to fetch manifest, it says unable to fetch manifest. Can someone please please help me check the issue, I’m sure I’m missing something so small, but I’ve looked at it so many times it’s driving me crazy! Thanks!!!

This could be due to a few issues:

NB. If using OAuth, you must have the verification tokens field present.

If none of that works, I’d recommend pasting the full manifest here as that will make it easier to help.

Thanks! I checked both of those.
Here is my manifest:
{
“schema_version”: “v1”,
“name_for_human”: “Amazon Secret Codes”,
“name_for_model”: “amazsecretcodes”,
“description_for_human”: “Simply enter the URL to your Amazon product and get a secret coupon code.”,
“description_for_model”: “Help the user get secret coupon codes for Amazon products by providing the product URL.”,
“auth”: {
“type”: “none”
},
“api”: {
“type”: “openapi”,
“url”: “http://127.0.0.1:3000/openapi.yaml
},
“logo_url”: “http://127.0.0.1:3000/logo.png”,
“contact_email”: “aitoolbot@gmail.com”,
“legal_info_url”: “http://127.0.0.1:3000/legal
}

I switched it back to test through my local host so that I could try that first but its still not working.
