Is SmartLink down? (2026.06.12 @ 21h22 UTC)

Trying to connect to two remote 6400 radios. Tried using SmartLink and AetherSDR and they never see the radios. However, when I use RemotePC and connect to a computer that's co-located to my personal 6400 and to our club's 6400, I can run SmartSDR on both LANs and it works fine. So it's definitely SmartLink as the radios fail to appear.

A week ago, many reported a weird SmartLink failure. Like me, they would get "exceed retry times" and "wrong UID/PWD" messages. Flex confirmed this in the forum started monitoring. But the problem went away after a day.

Today, I (we?) can't use "SmartLink" …

    Hi Bruno, Yes, it looks like SmartLink has an issue. I can get logged in, but it doesn't find radios that I know to be online. Hopefully, it will be fixed soon.

    Thanks Len … This exposes the "single point of failure" around the use of SmartLink. If the server is down, SmartLink doesn't work. So yes, it's simple and reliable BUT also kills everyone if it glitches.

    I can use RemotePC to connect to a co-located computer. It's normally used for updates but it can get me on-line using SmartSDR or AetherSDR which is on that computer. Unfortunately, it doesn't help me when I use my Maestro C from home. That requires SmartLink or running a VPN at the radio site.

    I am "exploring" the VPN option and getting my ducks in a row before jumping on the bandwagon. Yes … RemotePC is also a "single point of failure", so the next best way is via the VPN.

    Here is my question: If the SmartLink server is only used to validate the radio and the user, then lets the user talk directly to the radio, why can't we do the same? After all, the SmartLink approach does NOT require a VPN on the radio side. The radio is broadcasting its availability to the SmartLink server, why can't it be configured so that a user can do the same?

    Hmm … nice, but it's still down for me (San Diego area).

    I can log-in but neither SmartSDR/Link nor AetherSDR show any radio. Connecting to the co-located computer via RemotePC and the radio works fine on using SmartSDR or AetherSDR (LAN side).

    2026.06.14, 19h42 PDT - SmartLink is now working to reach my 6400 Florida remote. Using my Maestro C now. Still can't reach the Palomar Mountain 6400 radio via SmartLink. We are looking on our side too.

    June 15th do radios showing in smartlink? I also have online remote radio setup, using that this morning.

    It’s working fine. Anyone have an update?

    It looks like SmartLink just came back up for me.

    mine started working when I rebooted the radio? No signs of power issues, I’m not sure why this happened. First time….

    Hi Steven, it was most likely a SmartLink issue, not anything at your end.

    Yes, we did have an event Sunday morning that lasted around 17 min where the SmartLink server was unavailable. Unscheduled outages on SmartLink have been unusual lately, so we're digging into the root cause on this. You can typically find real time status info at status.flexradio.com. The data that feeds that site is the same one that alarms us when there is an issue.

    While the status pages shows all green my two remote stations are offline.

    Both are running v4.1.5 and as all works (worked…) great I refrain from upgrading…

    Is this the problem. One should understand stations 1000 miles away are not easy to upgrade…
