Hi David,

I'm still having issues. My Zscaler version is 4.1.0.9.8 and my Deco (x55) firmware is currently 1.3.1.

Web browsing or trying to access files etc. is extremely spotty and mostly unusable. My deco is also my router (connects to the modem) so I can't set it as access point mode. Have tried your static DNS as well to no avail. Internet connection type is PPPoE (IPv4).

is there a firmware for the x55 that solves this? I've had the deco for about a month and it has never really worked consistently when using zscaler while everything else works fine.

thanks

Just reporting I have the X73-dsl.

This firmware update has fixed my authentication issues with Z-Scaler. All seems to be working well.

Thanks.

I'm using a mesh of 3 Deco XE5300's, and having issues wtih Zscaler that sound similar to what was described in this thread.  The viability of the connection seems to come and go, sometimes I can't get to a website/service, then a few minutes later I can, or vice versa.  This happens whether or not I am tunneled through to my corprate VPN on top of Zscaler.

Just as an example, I've had 38 Zscaler notifications logged in the last 6.5 hours that seem to indicate the connection was unstable and came back up.  Yesterday I was working in a different part of town on a cellular hotspot instead of my home network w/Deco, and had no such notifications over probably a similar period of time.

Firmware version: 1.2.8 Build 20230901 Rel. 36505

Internet Connection Type: Dynamic IP

Hi David,

Is the TP link team planning to address this? I'm now unfortunately out of my return window and the Deco X55 clearly does not work with Zscaler.

I presume this is still because zscaler is still being blocked by deco which I cannot turn off.

I've been on the latest 1.31 firmware you released two months ago and it still does not work.

Looks like this is an issue with X50's V2 as well(in the above post it only mentions V1). The Deco's are X50's running firmware version 2.0.6 Build 20230928 Rel.882. I'm having the same issue with Zscaler on my worklaptop ever since I switched to an ISP that uses Deco's as the primary modem/router. Currently on Zscaler v3.x but in the process of getting company IT to install v4.x

  @David-TP 

Thank you for the prompt response David. To answer your question - the ISP in question is Distributel. 

So is the fix already available and the issue is they just haven't integrated/merged the patch into their firmware distributions? Would you suggest just pointing them to this thread for them to get the context of what the issue is and how to resolve it? I've just seen this movie before - just want to make sure they have all the information that they'd need in order to quickly resolve this. Instead of just saying that it's an issue with TP-Link and that I'd have to contact them

  @David-TP I have recently purchased Deco X55 Mesh Wifi-6 router and have hit this issue when running zscaler on my work laptop. The zscaler version is not controlled by me and is commonly installed by the corporate team. So this is making my X55 unusable with my work system. Can this be resolved immediately on X55 main line firmware. I dont know how this has not been fixed when zscaler is so widely used VPN. 

Thanks

Hi David,

Can you follow up with me via email or let us know timeline for a fix?

I noticed an update for the X55 released about a month ago (now 1.4.1 Build20231122 Rel. 40485) but zscaler still does not work on these routers.

I've spoken to our company's IT team and this is our only VPN option so have been left tethering from my phone instead.

It would be really good if I can get a fix ASAP. I use the deco as I have other TPLink products (smart plugs, cameras, lights) on the IoT network but it's been months and clearly the Deco does not work with zscaler.
