So ill preface by saying I've talked to the mods of the server and they claim its a client side issue. The mod pack is BeyondBerk
I was playing on a server without issue for almost 2 weeks when one of the dimensions, one similar to the overworld called resource world was reset, new map new items. The server had to go down for a few hours for this to take place and once it came back online I couldn't join for more than 5 minutes at the longest before getting kicked out, with most of my join attempts ending seconds after joining.
When I do manage to join it is either really laggy and then kicks me, or I just fall through the world for thousands of blocks and then it kicks me, there are several different messages like timed out or disconnected that occasionally pop up but the most common one is the one in the picture.
To try and fix this I have
-Restarted my computer (a lot)
-Restarted my Wi-Fi (a lot)
-Used the Curseforge/Modrinth repair tool
-Switched from curseforge to modrinth
-Deleted and redownloaded the modpack (on both launchers)
-Updated Java
-Used both the version of forge I started playing the server on and the newer versions
-Failed to use a vpn (my computer refuses to acknowledge me as an admin when i try to install them or it just doesn't show the download page)
-Tried using a different wifi signal (phones hotspot)
-Tried using direct connection to the server instead of saved ip
-Using less and more ram( the server starts at 6gb but I usually use 10)
-Lowering render distance (the server limit on render distance was already like 5 or 6 chunks but I lowered it just in case and nothing happened)
-I also think I flushed DNS not 100% certain if I succeeded it was about a week ago this issue started
-probably other things I cant think of at the moment
I am still able to play on other modpack servers just fine and I know at least 2 other people on this server are having similar issues, although their games crash whereas mine just kicks me.
