strain gauge _ wheatstone bridge_Hx711

I'm trying to read voltage from a strain gauge (Omga brand) by using a wheatstone bridge.
I'm using Hx711 for amplifying. I double checked everything but every time I received strange outputs.
Sometimes the value increases and sometimes it decreases. Also, when I'm bending my strain gauge the values change out of a usual trend of increasing or decreasing.
I replace strain gauge with a resistor to check whether the strain gauge is working or not ,but still the same problem is remained.

Using HX711.h library and Basic example.

Output with 4 resistor:

Ordinary resistors will have too much thermal drift, you need 0.1% low-tempco resistors
or better ideally, 1W or above (to reduce self-heating). In a real strain guage the 4 elements
are overlapping and thus have extremely good temperature matching, and glued onto a
lump of metal (and thus heatsinked).

In a bridge circuit like this variations are measured in microvolts, so high precision is needed.

A schematic would be great

How to make a schematic you can post

and post your code too please - between code tags.

Could be one of the HX711 boards where the E- ground connection is missing.
See post#23 here.
