just got my used unit home. it booted up fine first startup, but i couldnt login so i tried the reflash-method. and now it seems it wont boot at all. the ethernet-connection lights up and flashes, but i cant seem to get any ip-address to sign in to the miner.
what am i doing wrong and what can i do to fix it? unit has been loading for 10 minutes now.

i even tried reflashing it again, with the newest firmware available.
its a full-node package and im using my own 1600W EVGA T1 power supply.

help PLS!

//edit//

Red light on front is lighting up solid, a small green light is lights up on the blue controlboard, a red LED is lighting up right next to the SSD, and it looks like a red light is lighting up below the controlboard towards the hashboard?

Ciao Emilio1992, I also have the same problem as you for days and days and I almost went crazy trying to solve it, maybe I succeeded. Last night I wrote to Futurebit support and they replied that most likely my Apollo BTC Miner goes into temperature overheating and therefore to deactivate the mining process until the node is fully synchronized. Probably the mining process together with the download of the blockchain and the synchronization of the node in addition to an environment that is not cold but at ambient temperature (about 21 ° C) overheats our Apollo BTC too much and disconnects from the network to avoid damage from temperature or operation . In fact, when this happens I turn off the miner for about ten minutes and when I turn it back on the IP reappears and I can access it from the web dashboard. Now I have turned off the mining process and I am only synchronizing the node (I have reached 98%) when everything is synchronized I will start the mining process and see the results. However, I have already ordered two 120mm fans on amazon to be placed on the sides to cool it even more. I hope to solve bye...

This happens because small (40mm?) fan underneath Orange Pi 4 controller has been artificially slowed down by using 3.3V instead of default 5V. This causes overheat of the controller. It's a design flaw and should be fixed by manufacturer.
Adding two 120mm fans to cool down tiny controller is total overkill, what you should do, is to fix this small 40mm fan, not adding more fans.

How did you fix this? By buying a 5v fan?

Also according to this, going with 5v fans add about 10 decibles to noise but I didn't see a huge cooling improvement:
