IPFS hash link keep loading without not responding

[0xisk]

Hi,
I'm trying to add many JSON files in IPFS using the following API:
client.add('item.json')
And here is the output of the item.json file
{"name":"Musk","description":"description","image":"https://ipfs.io/ipfs/QmP8ZD7YrSyPWaU1UnTD9jFR6rwokncCCd3WK7f7eSJi11/0003.jpeg"}

The returned hash for this item.json works successfully, but when I'm trying to add another JSON file that's slightly different from the first one, the output IPFS hash keeps loading for a long time without any outputs.

And here is the output of the second item2.json file
{"name":"Musk2","description":"description","image":"https://ipfs.io/ipfs/QmP8ZD7YrSyPWaU1UnTD9jFR6rwokncCCd3WK7f7eSJi11/0004.jpeg"}
And that happens also many times if I just changed the name of the value with anything other than "Musk".

And when I try with localhost IPFS domain it works http://localhost:8081/ipfs/<hash> but not with the main ipfs link https://ipfs.io/ipfs/<hash>

I need your help to understand this behavior.
Thanks.

Do you have a script that can reproduce this?

This happens if your IPFS server is the only server with the requested content, but port 4001 cannot be reached from the public Internet. For example, if you run IPFS on your desktop or laptop, and do not have port 4001 forwarded on your network from the outside all the way to your server, your server is unreachable to HTTP proxies (e.g. ipfs.io) and unreachable from other IPFS servers - and so is the content.

You can fix this by either setting up the port forwarding, or by running IPFS on a server with a public IP address.

Thanks so much for your helping,

Yes, I have, here is a simple Py script for reading (10,000 images) and uploading them to IPFS. Then doing some data collections in JSON files (10,000 JSON files) and upload them to IPFS. At the end writing all the IPFS hashes in files.

import json
import os
import glob
import ipfshttpclient

# Hashes for all the items
ipfs_hashes = []

# A list of image hashes after uploading to IPFS
img_hashes = []

# Hashes for all the JSON items
obj_hashes = []

# A list of JSON hashes after uploading to IPFS
final_hashed = []

# Reading all images from /items directory
with ipfshttpclient.connect() as client:
    ipfs_hashes = client.add('items', pattern='*.jpg')

for obj in ipfs_hashes:
    if obj['Name'] == "items":
        break

    obj_name = obj['Name']
    split_str_1 = obj_name.split('/')
    split_str_2 = split_str_1[1].split('.')

    image = dict({
        "name": split_str_2[0],
        "description": "description",
        "image": "https://ipfs.io/ipfs/" + obj['Hash']
    })

    img_hashes.append(dict({
        "name": split_str_2[0],
        "description": "description",
        "hash": obj['Hash']
    }))

    image_json_file = open("json_items/"+split_str_2[0]+".json", "w+")
    image_json_file.write(json.dumps(image))
    image_json_file.close()

obj_hashes = client.add('json_items', pattern='*.json')

for obj in obj_hashes:
    if obj['Name'] == "json_items":
        break

    item_json_hash = obj['Hash']
    final_hashed.append(item_json_hash)

json_object_hashes = json.dumps(final_hashed, indent=4)

hashes_json_file = open("hashed.json", "w")
hashes_json_file.write(json_object_hashes)
hashes_json_file.close()

json_img_hashes = json.dumps(img_hashes, indent=4)

img_hashes_file = open("image_hashes.json", "w")
img_hashes_file.write(json_img_hashes)
img_hashes_file.close()

And here is the output of IPFS daemon:

This happens if your IPFS server is the only server with the requested content, but port 4001 cannot be reached from the public Internet.

So do you still think that this is the same issue?
