Issues connecting OLED at OLED#1, OLED#2 works fine

I ordered the pcb using official gerber files with JLCPCB, all 5 PCB have issues on OLED#1, any pointer how to debug the PCB ? thanks.

Use a multimeter and check if the traces are connected correctly. Check the schematics on the website as reference.

I also ordered my boards from JLCPCB using the official gerber files. OLED #1 worked fine. I removed the header pins from the OLED PCB and soldered the OLED’s vias directly to the PCB vias (no pins) with the use of tape to secure it during soldering and a generous amount of flux. Tested with a multimeter to confirm no shorts before adding power.

I haven’t tried OLED #2.
