Server cannot send GET requests to anything (including auth servers)

I'm running a 1.20.1 Modded server off of a spare linux box, for me and some friends. The server has been running fine for about half a year, until I moved the server from my dad's house to mine (as he had been babysitting it for me, while I was in an apartment complex and couldn't port forward). I copied over the portforwarding rules from his router to mine (both of us use TP Deco mesh routers), plugged in my server to ethernet, and was able to see the MOTD both from within my local client and from https://mcsrvstat.us/ . However, whenever I try to join the server, I get an "auth servers are down" error. Looking at the logs, the server doesn't seem to see my initial connection attempt, but when my client shows the auth servers down error, the log says (with identifying info removed):

[17:49:52] [User Authenticator #2/INFO] [minecraft/ServerLoginPacketListenerImpl]: Disconnecting com.mojang.authlib.GameProfile@[PROFILE_ID][id=<null>,name=[MY USERNAME],properties={},legacy=false] (/[MY IP ADDRESS]:56087): Authentication servers are down. Please try again later, sorry!
[17:49:52] [User Authenticator #2/ERROR] [minecraft/ServerLoginPacketListenerImpl]: Couldn't verify username because servers are unavailable

[17:49:52] [User Authenticator #2/INFO] [minecraft/ServerLoginPacketListenerImpl]: Disconnecting com.mojang.authlib.GameProfile@[PROFILE_ID][id=<null>,name=[MY USERNAME],properties={},legacy=false] (/[MY IP ADDRESS]:56087): Authentication servers are down. Please try again later, sorry!
[17:49:52] [User Authenticator #2/ERROR] [minecraft/ServerLoginPacketListenerImpl]: Couldn't verify username because servers are unavailable

I don't know whether it's a red herring or not, but I'm hosting it on port 25555, not 56087 but am unsure if it trying to communicate to my ip via that port is normal or not. Looking at the logs, I also noticed that any mod that's trying to run a version check (or patreon check) is failing (message got too long, see reply). I've never seen anything like this in my years of hosting modded servers. Any ideas?

Can a computer on the same network manually send a Get request to the auth server?

DakewlmanjackOP•3mo ago

doesn't seem like it...

DakewlmanjackOP•3mo ago

This is the GET error message I got from python; seems like I can't even see the domain

DakewlmanjackOP•3mo ago

I can, however, send a GET request to any of the mods' version check URLs

DakewlmanjackOP•3mo ago

i.e. Supplementaries' https://raw.githubusercontent.com/MehVahdJukaar/Supplementaries/1.20/forge/update.json returns:

𝒟𝑜𝓂𝒾𝓃𝒾𝒸•3mo ago

Do a nslookup

DakewlmanjackOP•3mo ago

are the auth servers just down? or am I doing something wrong here 😂 (running an nslookup on my IP returns the expected info, btw; assumed you wanted me to look up the authservers)

𝒟𝑜𝓂𝒾𝓃𝒾𝒸•3mo ago

interesting, doesnt seem like im affected if the auth servers are indeed down i mean you look it up on your local machine

DakewlmanjackOP•3mo ago

oh, duh! Been a long day

DakewlmanjackOP•3mo ago

Do I have the right domain?

𝒟𝑜𝓂𝒾𝓃𝒾𝒸•3mo ago

I think its indeed authserver.mojang.com

𝒟𝑜𝓂𝒾𝓃𝒾𝒸•3mo ago

eh.

𝒟𝑜𝓂𝒾𝓃𝒾𝒸•3mo ago

seems like they use cloudfront's cdn network

DakewlmanjackOP•3mo ago

huh. What are the implications of that?

𝒟𝑜𝓂𝒾𝓃𝒾𝒸•3mo ago

dominic@MainDesktop:~$ nslookup authserver.mojang.com

you are indeed having a very weird issue that aside, try running a completely vanilla server and see if that works

DakewlmanjackOP•3mo ago

ok, setting one up now. Is the inability for the server to get mod version info related, or something else?

𝒟𝑜𝓂𝒾𝓃𝒾𝒸•3mo ago

i do not know, send the complete logs via mclo.gs

DakewlmanjackOP•3mo ago

Vanilla server (same port) works fine For anyone else who encounters this: I did a full reinstall of Ubuntu and puffer panel, then put my backed up server files (world, mods, config) into a fresh server on the new installation !solved
