@FortMax yes I had the same idea, likely an expired certificate. If so they then sold the product knowing it would stop working on a certain date but they did not disclose that at the time of selling it. Legally puts them in a tricky spot I would think. 

  @MatthewEngland 

thats the thing. are they obligated to support it forever? 

do the new cloud products use the same app? I was under the impression no, 

and do they need to continue to run the cloud servers for those products if its no?

maybe its already in the agreement that we all "agreed" to already :)

sucks but I hope they fix it. kinda sucks to have 4 of these and it be useless. would suck more of the person that said they got a fleet of them.

  @MatthewEngland i dont think so, i have few order nc260 and they work well.

  @FortMax besides some of nc450 works

  @Wpginterceptor 

Same problem on NC 450 but NC250 are working well.

Can we do something about this issue?

Many thanks 

  @adrgal  if they dont resolve it i wont be buying another TP-LINK product again!!!!

  @FortMax if they don't want to keep running those servers, at least give us an option for self-hosting

  @Wpginterceptor For sure, but they know about this problem? And when was this upgrade done?

Please all send mail with the issue to:

support.ca@tp-link.com

  @maglione66 Ok thanks
