No waterfall or spectrum in SmartSDR

Ok... What do we have here.... I tought it was a port forwading issue but SmartLink tells me it's all OK... 

When my computer is on the same network as the 6600 it works fine. This happens when I try to run from home (6600 is 180km away). It also works when I teather my Phone to the computer. This tells me that everything is OK at the remote side.

Before the 6600 I used a 6300 and there where no issues at all.

Any suggestions?

I'm working remote.

I had the same problem on my inbound firewall. Turns out it was a hardware setting on the user end NIC card.

What are you using for an inbound router?

Mike,
I’m using a USG from Ubiquiti. The other very strange thing is that when I connect thrugh my neighbours wifi it does not work either. We have the same ISP and I’m starting to suspect that they have done something... the ISP have upgraded (or downgraded?) some of the equipement.

Yes, I had the same problem.  However, I did a post in the community where I found that changing a hardware setting on my PFSense router solved the issue.   Just reading your other post, on a Softether VPN connection, the waterfall/panadapter was just fine.

It was one of the NIC hardware offloading parameters.  It was changed not to offload things like TCP segmentation or large receive offloading

I’d suspect a troop of pesky demented beavers have built a beaver damn upstream and shut down the waterfall.

Don't know if this is a step forward finding the issue but when I make the SmartSDR window smaller, I get the Spectrum back. However, No waterfall.

Made a 20sec video... Enjoy... https://youtu.be/B6K3CzBZmpU

(This is with SmartLink. When I use SoftEther VPN I have to make the window even a little bit smaller in order fo get the same result).

Ok, thanks. I tought a VPN should solve this issue. Isn’t that the whole point with a VPN. That all traffic is in the tunnel?

SmartLink is not a VPN tunnel. It works on a completely different set of principles and network protocols.

A VPN tunnel, if it is configured to bridge two subnets that have the same IP network address, will work as a remote access solution.

Yes, I know that SmartLink is not a VPN-tunnel. But there was a suggestion to set-up a VPN-tunnel, and I did that, and do not use SmartLink, but it still doesn't work.

Ok, still struggling with this... When I change the size if the window (making it about 1/4 in size of fullscreen) I get the spectrum back, But the waterfall is still not there. Is there any difference in how the data is hadled that could explain why this is occurring?

I am running into the same issue. In fullscreen on my laptop I cannot get a decent refresh rate and no waterfall. Tried several different connections over smartlink, The window resize trick atleast gets me back to being able to use the radio remotely with the pano but no waterfall.

Steve Hicks addresses this as a SmartLink bug, "#3" in this Community thread. SmartLink does the same thing in SmartSDR for Windows and in Maestro.
