Can't get terminal in dashboard to connect on any of my devices

For all of my devices the terminal in the dashboard will not connect to the host or container.

Connection error
Reconnect failed


Can you please give us the dashboard link of the affected application and also grant support access to it, so that we can take a look?


I believe I have narrowed down the problem to my company network has begun blocking outgoing connections on port 22 out to the internet. I was able to get this to work outside my company network. This must be a recent change as I’ve always been able to use SSH outbound from our network prior to now.

So I’ll take that up with our IT dept. In the meantime, is there anyway to change the default port on which the built in SSH server listens?

Hi @wraithfive,

The web terminal in the dashboard web UI does not access port 22 directly, but if you are on a restrictive network it is entirely possible that something else is blocked.

You can try using the dev console of your browser to see what exactly is failing when trying to spawn the web terminal.

If your device is in the restricted company network, it’s also possible that some services may not work properly. On your question, currently we don’t provide a way to change the default SSH port on devices.

Had a similar issue after a working for a while in two devices:
environment: balenaOS 2.29.2+rev3 on beaglebone black, sup. version 9.0.1. Chrome browser.
Issue: terminal would not spawn - something will flash on terminal screen for a second, then disappear.
Solution: Reloaded the page! Don’t know if something gets cached and the cache fails?

Hi @leowise and welcome to the balenaCloud forum!

If you experienced these issues today within the past few hours, there were some incidents with our VPN that would have affected access to devices (see this incident specifically:

If not, could you post exactly what browser you are using using a tool like

Yeah, thanks for the replay/info xginn8; the issue was resolved (by reloading the balenaCloud page) : )
In response to your question, i am using [Chrome 76 on Windows 10].
The issue was kinda weird, because I am using two devices, and when I would switch to one device, the terminal would work fine for that device, but if I then opened the other device, it would not work! So I was wondering at that point if it was the device itself, but I decided to reload the page and that fixed the issue!
