Hello Community!
Half a year ago I bought two Rock64 boards which I planned using as NAS devices with OMV and Nextcloud (main server and backup server). The boards was bought at the same time (same order (probably the same board)). Despite the age, I haven't start playing with them before this month. When I flash the SD cards with Etcher and plug them into the boards, it gets installed and I can reach the WebGUI from a browser after a short time (everything normal so far). After logging in, I meet the following problems:
- On the first board, everything works perfect.
- On the second board, right after logging in to the GUI, a "Bad Gateway" message appears in the middle of the screen. This pops up time by time by time, and makes it almost impossible configuring the system from the GUI. After many attempts, I finally got SSH with root login enabled, and this is where I need help from you 
Does anyone have a possible solution? I have read every "Bad Gateway"-thread on this forum, but neither of them helped my case...
The message looks like this:
<html>
<head><title>502 Bad Gateway</title></head>
<body bgcolor="white">
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx</center>
</body>
</html>

Additional information:
- The OMV image is downloaded from https://sourceforge.net/projec…ngle%20Board%20Computers/ (via the download page on OMV's home page).
- I have tried logging in to the GUI from both Chrome and Firefox.
- I have tried different SD cards.
- I don't know what the reset and/or recovery button on the boards do. Is it possible they may reset something relevant?
I hope there are some great minded persons in here which can help me fix my problem!
Best regards
Marius
