Can only reach one Client on Switch Interface

I have the following issue. I got a 3560x-24 Cisco switch. On port 14 there are 6 devices connected for Data collection.
(This is a company setting and not a home)

Those devices have two NICs that allow to connect them one after the other.
Between switch and devices there are two RJ45 to Fiber converters, one from copper to fiber and the other one back from fiber to copper.
Switch -> Conv. -> Conv.2 -> D192.168.1.155 -> D192.168.1.154 -> D192.168.1.153 -> D192.168.1.152 -> D192.168.1.151 -> D192.168.1.150.

They are all in the vlan 405. The VLAN is working properely on other Interfaces and devices.

Now to my problem... When I set a ping from my PC (VLAN 109, can reach all VLANs) i can only reach the device with the 192.168.1.150. All the other devices in between are unpingable. Interestingly when I plug my PC into the Converter and set a ping I can reach all the devices.
What configuration is wrong in my switch?

description energy-collection
switchport access vlan 405
switchport mode access
switchport block multicast
switchport port-security violation restrict
switchport port-security aging time 2
switchport port-security aging type inactivity
switchport port-security
no logging event link-status
speed 100
no macro auto processing
storm-control broadcast level pps 100
storm-control multicast level bps 500k
storm-control action shutdown
storm-control action trap
spanning-tree portfast edge
spanning-tree bpduguard enable

I am very thankful for every help you can give me. I am really out of ideas at this point.

Hello @deisenkrein 

Without port-security and storm-control configurations, do you have this issue also ?

Best regards

Hello. Yes. Even if i only have two lines...

switchport access vlan 405
switchport mode access

Thanks

First we must check if mac appear on 

Show port-secuirty mac 

Table if it appear then share output 

Second This connection is like connect sw to hub so I think you need half duplex not full duplex.

MHM

Also when I disconnect the last one x.x.1.150 I can reach the 151... I really dont get it

If that case then it can port-secuirty 

Show port-secuirty interface x
