Issue Details

I'm using ELVIS III with MeasurementLive to acquire data. When trying out to connect the hardware it always shows the following connection failed error message. I have this issue with either USB, Ethernet or Wi-Fi connection. This was working fine some weeks ago, but is not working anymore. How can I fix this?
Connection failed. Check USB connection or troubleshoot.
Connect the device's rear USB-C port to your computer. Click Connect to pair the device.

Solution

This error is caused by a compatibility issue between MeasurementLive and the latest version of Google Chrome (v89.0.4389.82). The recent update of the browser is blocking the Real-Time Communication (RTC) calls, resulting in a connection failure. A Corrective Action Request (CAR:1363204) was filled with the R&D Team.

So far, NI is recommends the following workarounds:
  • Use Mozilla Firefox with an ethernet connection to the ELVIS III, which has support for Measurements Live as of 26th August, 2021. If you require a USB connection, navigate to http://172.22.11.2/measure.html.
  • Downgrading the Google Chrome version from the latest one to 88.0 or older and blocking automatic updates
  • Using Slimjet browser on Windows computers*.
  • Using Safari browser on MAC computers.

Additional Information

*Digital I/O feature in MeasurementsLive is not working properly when the host PC does not have an internet connection. This was reported in CAR:1233664.
