Hi there @SENNA440, sorry to hear you're having some troubles with your Fetch TV set top box.
Try the troubleshooting guides on this page → https://www.optus.com.au/for-you/support/entertainment/fetch?id=2244 to see if they help fix your issue, in particular, the steps on this page → https://www.optus.com.au/for-you/support/answer?id=9823.
Are you able to perform a speed test and post the results here so that I can see whether your Internet speed is sufficient to run the Fetch TV service?
Ahh thanks for letting me know, @Senna440.
If resetting the set top box and completing the troubleshooting steps bring no joy, you may have a faulty unit and would need to contact us to organise a replacement.
