**COMPLEX ISSUE** (?) - Players cannot join 1.20.4 server, met with "not enough bytes in buffer" err

Just plugged in my rig for the first time in a (1.20.4) while. The only change that has occurred is that there is now a PCIE wifi card supplying network instead of an ethernet cable. When the server starts, no sort of error codes appear in the console other than the "update me please!!" from my plugins. The port and same IP test as OPEN on any port checker website. Again... literally nothing has changed. I even tried not using a custom install of 1.20.4, to no avail. This is all very tortuous to understand, at least to me. Any help is much appreciated. THank you

to clarify - the error recieved upon trying to join reads "not enoguh bytes in buffer, expected 11 got 6"

Only thing I can think of is to double check the server installation version matches your player's client-version

update ... now the error is "failed to decode packet, clientbound/minecraft:login_disconnect"

likely bad wifi card, missing drivers or something like that if that's really the only thing that's changed, you can pretty much narrow it down. self hosting a server that's on wifi is... kinda crazy

downloaded both intel and asus drivers for it. if curious its an asus ax1800 yea its a temporary solution

why can't you continue using ethernet? this issue likely has nothing to do with your server config, sounds completely networking related, unless there's something in your logs that says otherwise

im on a home network .. nothing special nor oriented towards 24/7 server-open-ness ... im not exactly 100% sure but i think I burned out an ethernet port
Torrent
Torrent8mo ago
that would read a different error, the default is outdated client or outdated server

one day the ethernet just stopped working. Not the port on the mobo, not sure if it was the cable tbh, but the port on my modem that it was plugged into doesn't give connection anymore
Torrent
Torrent8mo ago
modem could be past its use
Astanar
AstanarOP8mo ago
wait actually im pretty sure it was the cable ... Im gonna need to trouble shoot

could also be why you're having this issue

I mean, no such "networking" ethernet cables exist no? they're all just copper wiring ? yeah true

Usually correct yeah, but I had seen it occur a few times with versions like 1.20.2, and 1.19. Doesn't seem to be the issue here though

1.20.x has this issue infamously almost, so many github / reddit posts about the very issue in different variations i digress, i will have to look into re-attaining ethernet

Torrent8mo ago
well i think this is an issue with your home network
Astanar
AstanarOP8mo ago
yes obv youre not spectrum support, but what do you reccomend as a modem more fit to this sort of load?
Torrent
Torrent8mo ago
it really depends what you're willing to spend tbh i've had bad luck with buying fancy gaming routers and the like
Astanar
AstanarOP8mo ago
i see

maybe someone here could make a good recommendation, but for now i'd try - restart your modem and server - temporarily disable your firewall to see if that's the issue - make sure your client and server versions match - have someone else join the server and see if they get the same issue

im looking for a very short term solution .. do you think this is one of those rare situations that i need to put the ip of the wifi card in the "serverip=" section of server config? thank you for your suggestions
Torrent
Torrent8mo ago
you should be able to see you IP in settings -> network & internet -> advanced -> hardware and connection properties
Astanar
AstanarOP8mo ago
it did NOT work btw
Torrent
Torrent8mo ago
it will detect your configuration btw
Astanar
AstanarOP8mo ago
oh
Torrent
Torrent8mo ago
i have a Killer E3100G 2.5 Gigabit Ethernet Controller and it has been very stable
Astanar
AstanarOP8mo ago
i just did a ipconfig in cmd, is that any different?
Torrent
Torrent8mo ago
shouldn't be, they're both reading the same thing but yeah i'm prettyyy sure something is either bad with your modem (past its use) or your wifi card doesn't really work or is configured incorrectly
Astanar
AstanarOP8mo ago
i have a feeling its the wifi card yeah

Are you able to run a Minecraft client on the same machine that runs the server? Do you get errors logging in if you type in localhost?
