I am having an interesting issue with a new ER8411, I have searched around and can't find any information on how to resolve it for this Omada router (although there are solution for other routers)

I have a very simple setup, Telus ISP modem -> ER8411

The problem is, that file downloads will always fail if they are over HTTPS, testing over CURL gives this error

```

curl <any file url> -o arc.zip  
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0  378M    0  476k    0     0   865k      0  0:07:27 --:--:--  0:07:27  864k
curl: (56) LibreSSL SSL_read: LibreSSL/3.3.6: error:06FFF064:digital envelope routines:CRYPTO_internal:bad decrypt, errno 0

```

The interesting thing is, I had the same problem with another router, and the solution was to disable GRO (generic receive upload) uaing the command `ethtool -K eth8 gro off`

I have tested with many routers

Modem -> Mikrotik router: Works fine

Modem -> Omada ER605: Works fine

Modem -> Omada ER8411: Errors

Modem -> Unifi router: Errors but fixed by disabling GRO
