login error code: 4
Every time I run the program, it keeps showing this error:
[2023-11-27 21:33:33] [hk.zephyr.herominers.com:1123] login error code: 4
What does this error code represent? How can it be resolved?

OS:Ubuntu 18.04.5 LTS
Cuda: Cuda compilation tools, release 11.8, V11.8.89
GCC:8.4

Is there any other information that needs to be provided?
