How to Solve SHSH HOST Not Woking? 3 Proven Ways to Fix it !

Part 1: What is SHSH?

SHSH is a special code that Apple gives to every iOS version. It helps your iPhone know which iOS it can install. When you update or restore, Apple checks this code.

But Apple only allows the latest iOS versions. If you want to go back (downgrade) to an older version, you need to save your SHSH blobs before Apple blocks them.

Websites like shsh.host help you save these blobs. Later, you can use them to downgrade your iPhone, even if Apple doesn’t allow it anymore.

So, host SHSH blobs = your key to downgrading iOS.

Part 2: [Downgrade Failed] Why Is SHSH Host Not Working?

Seeing shsh.host not working can be frustrating, especially when you're trying to save SHSH blobs for a downgrade. Here are the common reasons:

Apple Servers Are Down Sometimes Apple’s servers don’t respond. This blocks SHSH saving on any tool. Waiting a bit usually solves it.

Device Not Supported Very old or very new iPhones might not work with SHSH Host. It may not support your model yet.

iOS Version No Longer Signed SHSH blobs can only be saved for iOS versions that Apple still signs. Once Apple stops signing it, the tool won’t work for that version.

Network or App Issues Poor internet or an outdated app like 3uTools can also cause errors. Updating the app and checking your internet often helps.

Part 4: Fix SHSH Host Not Working via Check Network Connection [Basic Fix]

Sometimes, SHSH Host doesn’t work simply because your internet connection is unstable or weak. Checking your network can solve the issue quickly without using any tools.

Steps to Check Your Network Connection:

Step 1: Open your browser and visit any other website to confirm your internet is working.

Step 2: Try changing from Wi-Fi to mobile data or vice versa. Public or slow Wi-Fi may block access to shsh host.

Step 3: Turn off your Wi-Fi router for 30 seconds, then turn it back on. This refreshes the network connection.

Step 4: If you're using a VPN or proxy, disable it temporarily. These can block or slow down access to shsh.host website.

Step 5: Use tools like Speedtest.net to check your connection speed. A slow connection can cause SHSH Host errors.

Part 5: Fix SHSH Host Not Working via Server Status [Within 2–5 Minutes]

One major reason why SHSH Host does not actually work is the fact that Apple had stopped signing the iOS version that you are attempting to save. When the iOS version is unsigned, the SHSH blobs cannot be requested or saved by any means in any tool.

Follow these steps to check the server status:

Step 1: Open a trusted iOS firmware signing status checker site Look for exactly the iOS version that you're trying to use.

Step 2: A green checkmar along with that version means that the version is still signed by Apple and SHSH Host is working.

Step 3: When you see a red cross, it means that at that point, this version is unsigned. You need to get a version that is still open.

Part 6: Fix SHSH Host Not Working via Reconfigure Hosts File [Within 5–10 Minutes]

In some cases, the hosts file on your computer may block shsh.host. Any misconfigurations and the remnants of some old tweaks might stop the tool from functioning correctly.

Steps to Reconfigure Hosts File:

Step 1: Open the location of the hosts file

In Windows, press Win + R, write C:\Windows\System32\drivers\etc, and hit enter. On a Mac, open up Finder, Cmd + Shift + G, and type in /private/etc.

Step 2: Open hosts file as Administrator

Right-click on the hosts file and choose to open it with Notepad (Windows) or TextEdit (Mac). Ensure you do so with administrator rights.

Step 3: Look for Blocked Apple Domains Find lines like 74.208.10.249 gs.apple.com or any that mention Apple servers. These may block SHSH services.

Step 4: Remove or Comment Out Entries Delete the suspicious lines or add # before them to disable. For example: #74.208.10.249 gs.apple.com

Step 5: Save and Replace Hosts File Save the file, and if needed, drag it back to the original folder. Choose “Replace” if prompted.

Step 6: Flush DNS Cache To apply changes, open Command Prompt (Windows) and type: ipconfig /flushdns On Mac, use Terminal and type: sudo dscacheutil -flushcache and press Enter.

Step 7: Try Accessing shsh.host Again Open your browser and go to shsh.host. It should now work properly if the hosts file was the cause.
