I have a problem

Tags: #<Tag:0x00007fb5e0720158>

as I attached the pictures I tried to put in librenms olt c300 and he doesn’t want to make fun of me anymore and I don’t understand where the problem is from

I gave the order ./ln s dev: check and I see what I attached in the pictures

I admit in this software I’m a bit junior and that’s why if I can ask for help, thank you
