»Gold farm/Zombie Pigman Farm not working.

I'm an active member in survival and i built a gold farm recently with 4 23x23 nether portals,after i finished it,i was watching the portals for a few mins and no pigmen spawned,i don't know what the problem is,but if it's a bug/glitch,please fix it I would really appreciate it if anyone who knows about gold farms or any staff member can checkout my farm and tell me if there is any problem with the build.
Thanks.

Dude! It takes time! for ZombiePigman! and Also taking server mob lag into the count it may take forever!
I am not an expert with these fancy stuff!
Btw tag some staff mate

@TheRSC (Is there anychance u can help my buddy @TheLoliyat36 ?)

 

Some photos could help, it is hard to see what is the problem @TheLoliyat36

 

unless something changed ( and NOTHING ever changes ) gold farms do not work in survival.
portals don't spawn pigman.

this is not a new thing , for at least the last 4 resets this didn't work, and probably longer

 

I'm pretty much doomed then,all my time spent on this gone to waste (9+ hrs) i cri.
RIP

 

xD! They must be allowed man geez!!

 

Gold farms do not work on the survival server man. Pigmen cannot get inside the Overworld from the Nether through the portal.
