The Programmable Intelligent Computer (PIC) chip controls the power initialization sequence on each hashboard. If the PIC chip firmware is corrupted, it will not power up the domain lines correctly, causing the initial handshake to return unexpected data. Micro-soldering equipment is required to re-flash or replace the PIC chip. Failed First ASIC Chip (U1)
The client and server may not be able to agree on a common TLS version. For instance, the server might only accept TLS 1.3, while the client only supports TLS 1.1. 2. Misconfigured Cipher Suites

If you have administrative access to the server, look at the access and error logs for your web server (Nginx, Apache, IIS) or API gateway.
To resolve the 0x68 handshaking error, work your way from the application layer down to the network layer using this checklist. Step 1: Verify the URL Schemes and Ports Failed First ASIC Chip (U1) The client and
If you see "handshaking error unexpected response 0x68" on your terminal (or inside a diagnostic log), follow this procedure:
