Cannot build the sdrangel-docker project

[DerrickLau]

I ran the build_server.sh script in f4exb-sdrangel-docker folder and failed with this error:
=> => # [ 70%] Building CXX object pluginssrv/channeltx/modfreedv/CMakeFiles/modfreedvsrv.dir/freedvmodbaseband.cpp.o
ERROR: failed to receive status: rpc error: code = Unavailable desc = error reading from server: EOF

What does the error mean?

[f4exb]

error reading from server

Try to re-run...
