Antivirus programs, firewalls, or VPNs can block communication between Apple servers and iTunes.
6. Storage or System Conflicts
Low storage space or background processes can interfere with the restore process.

In rare cases, the error is caused by hardware issues such as:
- Baseband IC failure

In these cases, a basic iPhone Error Code 4013 fix may not work.
