Blynk client setup for Particle Rpi

My having a Blink fart. I had Blynk client running on RPi using the Particle agent successfully a couple of months ago but now the Blink client won’t connect to the device. Can successfully see device in Particle and Blynk consoles. Confirmed auth code is correct for Particle code. Can compile and download code to particle agent running on Rpi. But no luck getting it to connect?

Any ideas??

What device name should I be using on Blynk client?

Also running Blynk on local server with logs showing multiple devices are joining. Other Blynk programs work on different device but not Rpi.

Help. I’m out of thinks to try and open to suggestions.
