the laptop is not getting the internet when I connect through RJ-45 to one of the ports

[Lagerangelov]

I have 12 switches in the stack (1 commander and 11 members ) .All the 9 members have same configs and can connect it to the internet when I console it into the port of one of switches .The last 2 switches are causing an issue. When i tried to plug into the switches through rj-45 , I am not able to get the internet connection . The below config is same for all 8 switches and they work fine . Can someone help me if Im missing something in the config ?

Configs :

RD-3500yl-48g-11# show config

What VLANs are you trying to get access through?  If the other "member" switches are configured the same and work make sure that the uplink switches (connected on ports A1 & A4) are also tagged on the appropriate VLANs.  In other words, check the VLAN port membership on these two switches:
A1 28 92 4a 6e ec 40 | HP J8693A Switch 3500yl-4... S
A4 40 a8 f0 14 23 00 | HP J8693A Switch 3500yl-4... S
