@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

  @StuartF 

I have had the exact same issue

unfortunately on saturday I purchased a new c660 camera and have had issues since.
 

Camera has been returned but my other cameras and smart plugs are not working on remote 4g/5g.

Router - Deco x50

NBN - Optus

P100 smart plugs

C200 Cameras

You can setup a VPN with your deco app, then add the tapo devices to the VPN client list. Just setup my x20 deco and it works ok notifications are a bit laggy for doorbell and cameras.

Same again today (30th), everything fine around 1am but shanked by 7.30am. Trying my best to get Optus to look at it, provided as much info as I can. A fellow on Whirlpool has said they have had problem with point of sale stuff that uses websockets so that's a potential path to investigate. Bypassing optus with another ISP or VPN seems to fix it all so most definitely Optus are the common ingredient in this stew.

  @StuartF Phoned Tapo tech support last night to report the problem and emailed my device MAC addresses as they requested. Both the H200 hub and D230 doorbell camera changed to solid green light so internet access re-established. Initially the doorbell camera showed "local access only", but changed a couple of hours later to remote access. All still working this morning. Fingers crossed the issue has been resolved.

  @Guy_O Fixing this one MAC address / device at a time isn't a solution for the masses, sure it's got you up and running but a much more robust and broad fix is clearly required. I'm sure tp are working on that because optus as usual seem to be literally worse than useless.

  @Jascro Just received this email from TP-Link Support ... 

"We have identified that a recent update on the Optus network (ASN 4804) may be causing issues with the remote management of Tapo Smart Devices. We're taking this matter very seriously, and targeted cloud service switching was performed on December 29th to optimize stability.

If you encounter this problem, please restart your Tapo devices; the issue should resolve itself. If the problem persists, please provide your ISP and device MAC address for further analysis."

Hope that helps.

My cameras are almost back to 100% today.
I can connect and view saved footage on the SD card. However, it's not uploading footage to the cloud. 
It stopped uploading footage around 8am in the morning, and I'm not getting motion detection notifications either.
