Weird Echo when recording live sessions

[MLandgrebe64]

Hi,

Trying to get the online practice going for my band with all the pandemic restrictions around but having the same echo issue trying to practice with my drummer.   His audio to me was clear from his electronic drums + backing tracks from computer + mic.  
However on my side I got an echo on both my mic and guitar.  

First connection set up:

Guitar > Helix > mixer ( 2 channels stereo L+ R)
                                                                           > output into both inputs of Focusrite Scarlett 2i2 > to computer
Mic > mixer


Second connection (no mixer) set up:

Guitar > Helix > Focusrite L channel
                                                            > Focusrite to computer
Mic > Focurite R channel 


No matter what combination got echo on both vocals and guitar

Any ideas on where the issue might be coming from?

my internet speed is avg 347 download and 356 upload 1ms latency....my drummer is running about the same speed.

Thanks for any help on this

When the drummer muted his audio in to the session the echo went away.  Tried muting one of his inputs into the session but no luck.

Any good/helpful advise is welcome!

Thanks!
