honestly no one having issue with unable to log back to webgui??
I had an issue logging in via the web gui after my unit was hacked.
If you wanna reset your miner to default settings & password, then open the Avalon remote app and remote the miner.
Disconnect the miner.
Then power it back on and press the FUNC function key (before the indicator flashes red), for five seconds until the white light flashes to indicate success. Then press RESET or disconnect the power to restart. Then add back all of the network credentials via the app, then connect to the web gui.
You might need to a couple of factory resets for the login credentials to revert back too root/root
I bought a couple of these to dip my toe into bitcoin and to replace the space heater running in my basement. I'm having a lot of trouble with one of them...I believe I reset the password for it using the phone interface with a password beyond the character limit and it got corrupted. I'm trying to hard reset the device using the instruction quoted above and it doesn't seem to be responding properly. Holding down the top button when I plug in the cord it power cycles until I release the button. If I just hold it in for 5 seconds it boots normally.
In an hour of trying various combinations I got it to forget the wifi info once but it still had the bad password.
- well, no actual fire but the smell told me it's burned off "something!" This only mining 'Medium' level.
So this has been a waste of money. Seeing how many Avalon Nano 3's have issues, while some others do not, I'm definitively not going to buy another due to poor stability
