MAIXCAM runtime installation fails

I have tried to install the runtime on my maixcam:

1. connected maixcam to home wifi network, confirmed connectivity, attempted to install runtime. Error: "request lib failed"
2. connected to cellular hotspot, confirmed connectivity, attempted to install runtime. Error: "request lib failed"
3. connected to maixvision app, attempted install...it tries for a second then stops (no error message). Could not find any log files to check for error
4. attempted manual install via python script:

import os

def install_runtime(force = False):
    version_path = "/maixapp/maixcam_lib.version"
    if force and os.path.exists(version_path):
        os.remove(version_path)
    cmd = f"chmod +x /maixapp/apps/settings/settings && /maixapp/apps/settings/settings install_runtime"
    err_code = os.system(cmd)
    if err_code != 0:
        print("[ERROR] Install failed, error code:", err_code)
    else:
        print(f"Install runtime success")


force_reinstall = True   # reinstall runtime even we alredy installed.
install_runtime(force_reinstall)

start running...

-- [I] Current runtime version: 
-- [E] Install runtime error: no network
[ERROR] Install failed, error code: 65280

program exited

Start by reproducing the failure with the supplied Python script and the /maixapp/apps/settings/settings install_runtime entry point. Compare the reported “request lib failed” and “no network” results across the listed connection methods, and inspect whatever runtime diagnostics are available. Done means identifying why installation cannot detect or use the network and confirming a successful runtime installation or a clear actionable error.
