I made a previous post about this issue and have come to some conclusions, first i now know it is a networking issue though not entirely sure what is wrong. my previous post describes what the issue is but now ive changed a bunch of settings to do with my router and my friend was able to fully connect to the server and interact for about 5 seconds when he stopped moving server side and eventually timed out. All packets are correctly sent (or at least i believe) port forwarding is done correctly and can be seen by canyouseeme.org and both me and my friend have good internet so if anyone have any ideas please consider helping previous post:

I have run the server on a second device and my friend had the same issues as before where he was in the server and could move client side but nothing happened server side but any blocks he broke near his actual player did break but that was it, after a while he saw things move but it was around 2 minutes delay but this time he didn't get timed out This leads me to still believe it is an internet issue but i have no clue what it could be as the logs say nothing about this and both of us have decent internet so maybe the router is limiting the amount of data that can be sent leading to the delay and eventual timeout.

ive checked firewall port forwarding dozens of times and im sure its all correct. my internet connection isnt insanely fast but still average. my friend has around 40 ping on the server. ive tried everything and believe it could now be an issue with my router however from everything ive seen this is really weird behavior. if anyone knows networking your help would be greatly appreciated.

I just tried with better mc and my friend has the exact same issue although it takes about twice as long for him to join the server I just tried a server with only jei and create and my friend did fully load in once but now is doing the same as before edit: he can join the server but just very rarely

Same as before even after reinstalling the server and updating most mods https://paste.ee/p/EkdNi here is my friends logs https://paste.ee/p/kAP4H

I removed it from the onedrive directory and removed essential and its still just lagging for my friend logs: https://paste.ee/p/gtXpz

I believe this is the same issue but with a different mod maybe so if someone could figure out if a mod is the issue ill link the server logs below Other persons issue: https://forums.minecraftforge.net/topic/123906-a-friend-of-mine-cant-join-my-lan-server-with-mods/ Logs: https://paste.ee/p/5VeQS#s=0

someone please help 😭

do i need to send any logs or does no one know how to solve this issue?

my modpack has around 150 mods but I've had this same issue on another modpack with around 80 mods the only time i could get a server working was forge with no mods and i haven't tried with a small amount of mods

I have made dedicated servers on my computer with no mods and have zero issues but for whatever reason when friends join my modded server they are able to join but cannot move server side but are able to break some blocks close to their player and after about 5 minutes they get kicked due to a timeout error sometime they can move and see me move but its about a 1 minute delay from when i actually moved I am able to join and everything runs fine just not friends I have checked my port forwarding and firewall many times over and there seems to be no issues and don't believe the mods are the issue but i could be wrong My best guess is that when my server sends data to my friends the packets are to large or too slow for it to update I'm not the best with technology and would appreciate any help as I've been trying to fix this for about a month now and this is a my last resort
