Before fixing the error, it's crucial to understand what SHSH blobs are. SHSH (Signature HaSH) blobs are digital signatures from Apple that verify a specific iOS version is allowed to be installed on your device. Apple only "signs" the latest iOS version (usually for 1-2 weeks after a new release).
Antivirus software or Windows Firewall often mistakenly identifies the connection attempt to Apple’s servers as suspicious traffic and blocks it.
