Hub v3 impossible to connect

Have I followed the correct instructions? Is there something wrong with the way I attempted to do this?

Hi @mslayre
Just to confirm, did you follow the NTP blocking steps mentioned in the post first?

45

The initial router setup doesn’t permit this, so I retrieved and swapped in a different router and performed the NTP port blocking instructions.

This resulted in the same error code 33-303

46

Could you send me the hub logs where you see the 33-303 error?

Troubleshooting

Capture the hub logs via a USB log dump using the steps below:

  1. Insert Fat32-formatted USB drive to the USB slot on the back of the hub.
  2. Press and release the reset hole on the back of the hub.
  3. Hub LED will blink magenta while copying logs.
  4. After the Hub LED returns to normal from magenta blinking, extract the USB drive and connect it to a PC.
  5. File name will be “logdump_xxxx.tgz.enc”
  6. Leave a comment in this thread and we’ll send you a direct message (DM).
  7. Then send the package via direct message (DM) to our SmartThings support team.

Can you provide a screenshot of the configuration, please?
