Hello Robert, It is well compatible with version 1.7.4; I had an issue with a pop up message coming out every 5 seconde telling me that bandwidth was lesss than a certain value and I heard a noise as well very 15 sec as if somebody knocked at a door.
I contacted directly Open Clove support, and they fixed the issue very fast.Don't hesitate to contact them : ovx-support@openclove.com, maybe they know if it is compatible or not with 1.7.3.
