@StuartF Having the same problem, it's more looking like it's Optus's issue..... I tried speaking to them earlier and they told me to try TP-Link support, which is sounding like TP-Link would like to send replacements although there's nothing wrong with our devices.....

Thanks  @Jascro

Monday 29th Dec 2025 - everything started working around 1am, earlier than the previous two days 3am. Tapo H500 hub connected to their servers / cloud, my tplink router could contact the cloud and my password reset link, while expired, also started working again in that it could contact the server. Around 7.10 to 7.15 am, things started becoming flaky, by 7.20am everything was once again offline unable to contact tplink servers / cloud as with previous days.

Glad it's not just me - I'm seeing the problem at the exact same times as you for the past few days!

I'm on Optus HFC NBN in Sydney

Modem is Sagemcom F@ST 5366 LTE

Firmware version SG4Y1L003075
