Bitaxe Supra 400 - "Gh*: 0.0 W/Th: inf"

[Vincnet64]

Hello,

Describe the bug I received my Bitaxe Supra 400 the last week, i applied the configuration notice and it worked only 2 days without touching. Since the screen displays "Gh*: 0.0 W/Th: inf" or "**Gh*: 0.0 W/Th: nan**" and I have sometime "Input Voltage Danger: Low voltage" on AxeOS web page.

To Reproduce I dont know...

Expected behavior Bitaxe working with a Hashrate.

Screenshots & Photos

Hardware (please complete the following information):

• Bitaxe Supra 400 (model (1368)
• PSU: EU 5V 4A
• Bitaxe HW vendor: D central tech
• ESP-Miner FW version: 2.1.0 intial
• Pool URL, Port, User: Public-pool.io 21496

Additional context I thought it was coming from the firmware, so I upgraded to V2.1.3 but nothing changed. Then I tried to flash it via https://wantclue.github.io/bitaxe-web-flasher/, by clicking on "Bitaxe Supra" but the screen of the Bitaxe, i had "Auto test, Power: Fail", then I I tried to clean everything via ESP Tool (espressif.github.io), then put back the "esp-miner-factory-401-v2.1.0.bin" and I came back to my original problem with the display " *Gh: 0.0 W/Th: nan**".

Could you help me because I'm lost. Does this power supply need to be changed (I am in France) ? Is it coming from the firmware? I appreciate your help....

Thx Vincent

Bad power supply. Change to a new one, at least 20W or higher.
