If the drive is disconnecting, which would cause the server to not be responsive, suspect it’s a bad or just crappy drive. Never heard of that brand and doesn’t have that many reviews.
Stick with name brand trusted drives not some random Chinese brand.
That drive comes up as $112 on Amazon whereas I’ve seen Samsung and SanDisk brands for around 80 or less. A WD portable ssd 1TB on amazon is $60. A Samsung T7 1tb, which is much faster than no name, is $80. (i used a T7 500GB)
Where does Channels recommend this particular Chinese brand SSD?
The only thing on the Channels web page under the Pi page is "WD Elements 4TB Hard Drive" and that is a powered drive.
Often those no name China drives are fake, and just a crappy micro-sd card on a pcb with a controller chip programmed to say it is larger than it really is, and when u write data to it, it starts overwriting existing data, and when u try to read that data back, ie play a video, it just craps the bed. (look at YT videos on Amazon ssd scams etc)
If you can submit diagnostics from the server that would help show what’s happening or perhaps have an HDMI hooked up to another monitor to observe anything displayed when it does crash.
