Hello,

I can't seem to get access to my camera DCS-933L on mydlink App (iPhone) when connected via cellular. I can access it outside of my home network via web browser or public WIFI on mydlink App so it can't possibly be a firewall issue. I just can't seem to connect to it via cellular and I have LTE so it's not a speed issue neither.

Can anyone help?

Thanks,
Tony

I am having the same issue. I can't access my camera via cellular on my iPhone. I can access over the web and wifi but when I try to go cellular using the app I get the following message:  "Could not connect to the device. Please try again later. (0.70_0_2_8_0)

Any help from D-Link or someone in the forum would be greatly appreciated.

Thanks

I'm not sure exactly why but cellular access to my camera seems to be working today.

I did enable port forwarding on my camera to see if that would make any difference. However, I also disabled it afterwards to see if that was the actual fix and I was still able to access it over a cellular connection. So I don't know if this is a permanent fix or not but if I don't have access again in the future I'll try enabling it again to see if this repairs the issue.

Thanks

was the cause of this ever determined?

My connection via my iOS when over mobile is now having the same exact problem.
Over wifi works fine.

Sorry no, I never got a solution but eventually mine did start working for whatever reason. I think it does have something to do with the cellular connection though because in some locations I've had it not work and in others it does. Sorry I can't be of more help. Good luck!

I had the same problem. The myDLink Lite app uses 3 connections to Amazon EC2 (the cloud provider for MyDlink). All TCP connections to port 2047, 2048 and 80. I noticed when I go to 3G/cellular (instead of WiFi) my port 80 connection was going to my Cell provider's (Bell Mobility) Web proxy which handles all port 80 traffic (which I thought was mainly for mobile browser not all mobile apps that use port 80). So I went into my APN (Access Point Name) settings on my phone, (under Settings->Wireless and networks->Mobile networks) and removed the Proxy address and Proxy port (80). This fixed the problem and I haven't noticed anything that is being blocked to port 80 when browsing so far.

Most likely my cell provider is using proxying web traffic on port 80 for speed (via cached content) and tracking. They may be blocking certain sites/things and could likely do that without the proxy also...only time will tell when using apps that use port 80 or more browsing time. Note I suspect each Mobile provider may have different policies for their APN settings and any content filtering,etc, so removing any proxy for port 80 may not work for all, but it is worth a try (just remember what you delete/change)

This worked for me.  I am on an LG G3 and using DCS-936L camera.
I was having problems accessing mydlink lite on cell network (Virginmobile.ca) but I could browse without any issues.

I don't know, but just maybe I've found the right thread here.
We've been experiencing the same problem ever since the latest firmware updates to the cams.
Now we haven't changed our router, modem, isp or phone. Everything remained the same.....except the camera firmware.
I have contacted DLink via email at least 4-5 times. The results were scripted answers. Called the 800 number....same answers. But the problem was passed to higher echelon techs. Still no remedy for not being able to connect via mobile data.
Our mobile device is LG model LGL33L; android version 5.0.1; kernel 3.10.49; software version L33L10. This is fairly new phone. And like I said before, everything worked and video was viewable on all our cams using the AP in the remote mode(cell data). ATT is the carrier. The APN name is TFDATA. I'm assuming that stands for Trac Fone DATA. Proxy; not set. Port: not set.

Here's my question: Is anyone else experiencing this new anomaly with Straight Talk/Trac Fone LG phones?
And do you have any ideas/workarounds?
It does not appear that we can change the default APN or its settings. But there is a APN settings field for a new APN. How do we try a different APN or is that even possible?
What sense is there in even having a mobile AP if it's only useful when we're near WIFI?? not very mobile is it?

Thanks

I can access my 933L via the Lite app just fine on 4G cell ATT and iPhone. I don't know about any other cell services. Also works on a iPad with cell service as well.

When did you contact D-Link support on the phone and did you get a case number?
IT might take some time for them to review and fix this issue.

My last phone contact with DLink was 1200 12/02/16.
Case # C6944075 was assigned.
Case was eventually referred to advanced level troubleshooters.
Waiting for DLink reply.

I would give it some time as see if they respond. If not, phone them back again. The problem maybe deeper than expected.

Same issue as user btp, using latest firmware for DCS-942L, Tmobile, IOS 10.2 on both iPhone and iPad, and Dlink Lite app version 3.6.7. (Worked fine with older firmware, IOS 9, and older Dlink app)

If connected via WiFi it works, If Cellular it gives error 0.70_0_2_7_70. (what ALSO does not work is viewing live video on a Mac running OSX Sierra using either the OLD plugin linked to one the live video page, OR the newer plugin I found on some Dlink support page.

But here is what DID work when using cellular... connecting the iphone or ipad via a VPN service such as private internet access. Doing this eliminates the cellular <> dlink connection, going through the VPN instead eg Cellular <> VPN <> Dlink

It's not a practical workaround unless you already use a VPN service, but it does seem to prove that Dlink is not handling the data traffic correctly to be compatible with the cellular carriers.

Link>Welcome!

  • What Hardware version is your DCS? Look at the sticker behind or under the camera.
  • Link>What Firmware version is currently loaded? Found on the DCSs web page under status.
  • What region are you located?

What Mfr and model is the main host router?
What wireless modes are you using?
What is the distance between the Camera and the main host router?


I recommend setting a static IP address ON the cameras outside of the main host routers default DHCP IP address pool as a troubleshooting step: 192.168.#.42  DHCP

Test cameras with uPnP and uPnP Port Forwarding both enabled on ALL cameras: DCS Cloud (L) Series Camera Configuration and Mydlink.com

Same issue as user btp, using latest firmware for DCS-942L, Tmobile, IOS 10.2 on both iPhone and iPad, and Dlink Lite app version 3.6.7. (Worked fine with older firmware, IOS 9, and older Dlink app)
