I have not touched on his transformer not being able to run the psu but if he does one board at a time and all work it could be an issue with the psu not getting enough power.
That is a possibility, but what are the chances that the kernel log wouldn't throw any power related error? it is usually best to start troubleshooting the obvious errors before speculating, a very common issue is the fan grill , during shipping and handling the grill can bend a bit, pushes against the fan's motor and as a result of the fraction created by the grill - the fans don't spin fast enough.
judging the kernel log, it is safe to assume that this is not a pool / internet related issue
2019-10-11 04:43:52.779] Pool 0 difficulty changed to 65536
This line wouldn't show up if the miner couldn't connect to the pool , so let's wait and see if replacing the fan/s will fix this issue.
I'll report back with a kernel log from it after keeping it running for 1-2 hours if I can.
It is safe to assume that if it does not start hashing in 30 mins, it will probably never start.
