@clever yew please attach any applicable log files and mod lists while waiting for help!

#

the backend server seems to work fine, we can send items to each other

#

i followed this guide and everything appears to be set up correctly, but clients still cant join

clever yew
#

this is the error we get

boreal cave
#

this is a P2P UDP issue. Make sure 25565 is open in the router and eft.exe is allowed in defender

clever yew
boreal cave
clever yew
#

looks like eft.exe is allowed

boreal cave
#

what about in?

#

out isn't usually the issue,

clever yew
#

working with another network security friend, he told me to check a different area of windows, and i found that this was disabled. could this be the problem?

clever yew
clever yew
#

just need to wait for my friend to test it again, will update the thread after

boreal cave
#

your home network is considered "private" so its not allowing connections to that program over your network

clever yew
#

i didnt expect there would be a firewall problem because we've been playing on 3.8.3 for months without issue

boreal cave
#

different folder probably

clever yew
#

would it be easier if a member of staff tried to join? idk what troubleshooting/debugging tools yall have

boreal cave
#

These are it. Lol

clever yew
#

hm, well i don't know what else to try :( already restarted pc and network

boreal cave
#

can I see your f12 settings?

clever yew
boreal cave
#

looks good. and this other person is outside of your network I assume?

boreal cave
clever yew
clever yew
boreal cave
#

you take the server one and he takes the other

clever yew
#

other person says it's not connecting

boreal cave
#

so your pf isn't working thrn

clever yew
#

is it possible the UPnP function on the router is breaking things? i noticed its turned on

boreal cave
#

maybe?

clever yew
#

what is NAT Punching? could that be a workaround?

clever yew
#

i doubled checked the firewall rules and it should be allowed

#

i'm 99% confident that i portforwarded 25565 to my pc with UDP, but i can't take another look at the portforwarding until later tomorrow

#

I just use ports I know so yeah

clever yew
#

for now im going to sleep

gn

clever yew
#

hey, just updating this thread to confirm that my 25565 port is forwarded. any ideas why it still seems to be getting blocked?

cinder folio
#

Show us the forwarding rule

clever yew
#

when i ping 6969 it works, but when i ping 25565 it says connection refused

#

gonna try using 19132 instead of 25565

cinder folio
#

You cannot ping UDP ports

#

#udp-tester

#

Use that tool

boreal cave
#

He used it

#

Can't connect

clever yew
#

i dont have someone else to test the udp tester right now, could you try it?

cinder folio
#

If that still doesn't work then your port isn't forwarded correctly, if you can guarantee me that the firewalls are open in Windows too

clever yew
cinder folio
#

Then your router is the issue

#

You can try enabling UPnP, change the port ingame and host

#

Or do it in the UDP Tester, whichever works.

clever yew
#

okay, ill update the thread again when i get a friend online to help test it

clever yew
#

well, in the mean time, i was able to get the UDP tester to connect to a client on 25565 UDP from the same network. i used a spare laptop

great news! it works! at some point after changing many settings, my friends can join my game. we had a great first raid. there was a weird bug where my alpha container was missing when i loaded in, and i could see a level 0 dogtag in my inventory. not related to the ticket, but i thought i should mention. i will resolve the ticket now
