Charging issues persisting after Lightning Connector replacement

I replaced the lightning connector via this guide, really good one. However, I still cannot charge my phone, but the mic and antennas work. I managed to charge the battery directly via an activator circuit and I can power up the phone without any problems. What could be the issue? It is the second lightning connector I try and I have had the same problem both times - everything works except the charging port…

Thank you in advance

Best regards
