[AVR Miner] Rejected (Username changed) but didn't change username

[Knochi]

Describe the bug Occasionally i get bursts of emails, that "some of my miners have invalid or inappropiate statistics". I got a "suspicious" tag on my wallet and in the AVR Miner log i can see those lines "rejected (username changed)..."

To Reproduce Steps to reproduce the behavior:

1. flash official AVR Miner 3.3 to "DFRobot Beetle" (leonardo clone, Atmega32u4)
2. connect to Pi400
3. start official AVR Miner.py

Expected behavior Mine DUCOs without issues
