Is a 'curl_error' a sign of a failing hard drive on the PS5?

While less common, a 'curl_error' *could* be related to a failing SSD, especially if it occurs consistently during multiple downloads or installations. However, it's much more likely to be a network issue. Before assuming a hardware problem, exhaust all network troubleshooting steps. If the error continues even after verifying network stability, consider running a storage check in Safe Mode or contacting PlayStation Support.
