Amazon “Something Went Wrong on Our End” With a Proxy: Fixes
What the page usually means, which checks to run first, and why a shopper's browser and a script need different answers.
The three most common causes
1. Amazon has a fault, or the link is bad. Amazon does not publish a list of reasons for this page. It showed up when Amazon's checkout failed on 30 August 2024, according to a news report, so seeing it once through a proxy tells you little. A saved or edited product link can also point to a page that is no longer there.
2. Something on your side is stale or in the way. Old cookies, a cookie cleaner, a browser extension, or a proxy that is only half set up (wrong protocol, port or login) can break the page. Chrome's help notes that deleting cookies may sign you out of sites that remember you, so remove Amazon's data only, not everything.
3. Automated or very frequent requests. Amazon's Conditions of Use say the licence to use its services does not include “any use of data mining, robots, or similar data gathering and extraction tools”. Amazon does not say which signal leads to which page, so treat an error after a burst of requests as a reason to stop and review the job, not as a puzzle to get around.
Turn the proxy off, or use a browser profile with no proxy, and open the same URL. If the dog page still shows, the cause is the page or Amazon: wait and try later. If it opens, go to Step 2.
Expected result The page loads without the proxy.
Step 2: Reach the item another way
From Amazon's home page, search for the product and open it from the results instead of the saved link.
Step 3: Rule out cookies and extensions
Open a private window with extensions off. If Amazon works there, remove Amazon's site data only and turn extensions back on one at a time. Chrome warns that deleting cookies can sign you out of sites that remember you.
Step 4: Confirm the proxy itself works
Run the curl test below with the host, port, protocol and login from My assets. A JSON reply with an IP means the proxy answers; an error means fix the proxy first.
Expected result JSON with the exit IP and country.
The country in the curl reply should be the country you bought the IP in. Use the same static IP for the same account every time; do not move an account between IPs to see which one works.
Step 6: Stop and ask
If only Amazon fails while ipinfo.io works through the proxy, stop refreshing and repeated sign-ins. Contact Amazon (Seller Support for a seller account). If the IP fails the curl test, send us a ticket with the order number.
Before continuing Chrome and Edge do not support SOCKS5 with a username and password, so for a browser use an HTTP asset.
Test the proxy with curl
# Does the proxy answer? (HTTP asset, port 2222)
curl -x http://LOGIN:PASSWORD@HOST:PORT https://ipinfo.io/json
# SOCKS5 asset (port 3333): resolve names through the proxy too
curl -x socks5h://LOGIN:PASSWORD@HOST:PORT https://ipinfo.io/json
Example only: replace LOGIN, PASSWORD, HOST and PORT with the values from My assets.
Symptom, check, action
Every Amazon page shows the error, other sites load through the proxy
Check Does Amazon load without the proxy, and in a private window?
Fix If it also fails without the proxy, wait. If it fails only with the proxy, run Steps 4 and 5.
Stop when One clean retry is enough; repeated reloads add nothing.
Only one product link fails
Check Open the product from Amazon's search results.
Fix Use the path that works. If the item is gone, there is nothing to fix on the proxy side.
Stop when Do not change IPs for a single dead link.
The error started after a script sent many requests
Check Is the use allowed under Amazon's Conditions of Use?
Fix Stop the job. Use an interface Amazon documents, or get Amazon's written permission.
Stop when Do not restart the same job on a new list of IPs.
The browser shows ERR_PROXY_CONNECTION_FAILED or asks for a login before Amazon loads
Check The proxy fails before Amazon is reached.
Fix Follow the proxy address and port guide and the proxy authentication guide.
Stop when If curl also fails, send a ticket with the order number.
What a proxy does and does not change
A proxy changes the address Amazon sees. It does not change Amazon's Conditions of Use, the standing of an account, or a decision Amazon has already made.
We sell IPs for ordinary browsing and for account work that follows Amazon's rules, and we do not give guidance on collecting data in ways Amazon prohibits. For a seller account, keep one stable IP for the account, do not share the login, and finish any verification Amazon asks for.
For a shopper or seller who opens Amazon in a browser, a static ISP IP is the usual fit: it stays the same for the whole lease. One IP costs US$0.50 for 1 day or US$7.99 for 30 days (about US$0.27 a day, 7.99 ÷ 30), the same in every country. There is no free trial, and stock for each country is shown on the order page.
The Amazon use-case page covers the setup for seller and buyer accounts.
Open My assets and copy HOST, PORT, USERNAME and PASSWORD. HTTP uses port 2222 and SOCKS5 uses port 3333 on proxy.proxy302.com.
Step 3
Enter them in the browser profile you use for this Amazon account only.
Step 4
Open https://ipinfo.io/json through the proxy and confirm the country, then sign in to Amazon.
FAQ
Does Amazon's “something went wrong on our end” page mean my IP is blocked?
Not by itself. Amazon does not publish what triggers the page, and the same kind of page appeared during a fault on Amazon's side. Run the checks above before you change anything.
Only if the current proxy is set up wrongly or its exit fails the curl test. Swapping IPs to see what happens is not a fix, and an account should keep one IP.
Can I use a proxy to scrape Amazon?
Amazon's Conditions of Use do not allow data mining, robots or similar tools, and we do not provide guidance for that. Use an interface Amazon documents, or ask Amazon for permission.
Why does the error appear only when I sign in to Seller Central?
Amazon does not publish a reason. Note the time and what you did, check the steps above, and contact Seller Support. Keep using the same IP for the account while you wait.
