Signal-K dashboard Not connected to server after upgrade to v3.50~15 (Firefox)

I have just upgraded my Cerbo to v3.50~15.

When I access SignalK via VRM (I am away from the boat) if opens SignalK dashboard, but claims that it is not connected to the server:

I can start SignalK WebApps, but most of screens on SK dashboard are empty (Data Browser, Server Logs…).

unfortunately I can´t help - just upgraded as well today and here everything works after the upgrade so it´s not a general problem… maybe you can try to reboot the cerbo manually from gui (that´s what I did after the upgrade - but I didn´t check signal-k before rebooting the cerbo).

Didn’t you customise your setup with a standalone install of nodered/signalk

@Tigrecito reboot helped. SignalK brought everything to normal.

@nickdb no, I use Cerbo’s SignalK and have only installed NodeRed embedded package for SK. So no modification of SK, just Cerbo’s NoderRed is not used (disabled).

Ok cool. When in doubt, turn it off and on again :wink:

great to hear :wink: … that is what I always do after any upgrade of venus os or after signal-k updates … rebooting the whole cerbo.

Update: this happens again. This time I have checked browsers console and this is the error message:

Firefox can’t establish a connection to the server at wss://386077-signalk.proxyrelay9.victronenergy.com/signalk/v1/stream?serverevents=all&subscribe=none&sendMeta=all.

At the same time, it works from my Android phone with Chrome browser.
It may be related to web browser…

Just update: I have tested the websocket with https://websocketstest.com/ and by default Firefox did not pass the test.

Then I started it in Troubleshooting mode (hamburger menu - Help - Troubleshooting Mode…) and it passed.

When I restarted it afterward in normal mode, it passed websocket test and SignalK over VRM proxy works.
