Minecraft Server "Failed to verify username!"

Technical Support
#1

OS Name/Version:

Ubuntu 20.04.4 LTS

Product Name/Version: (Always use the full version number - not ‘Latest’)

AMP Release "Triton" v2.3.3.4

Problem Description:

My Friends cannot join without getting the Error “Failed to verify username!” in the console. (can join other servers)
The Server mysteriously works for me, but only with my main Account.
If I use a Hacked client with an Alt Account I get the same error (works on other servers)

Steps to reproduce:

(Not known)
Problem appeared on fresh install

Actions taken to resolve so far:

-Checked DNS Resolution of Host and Docker
-Checked Ping (Host & Docker)
-Changed Instance from Host to Docker version
-Created New Instance
-Used Different Version and Distribution
-Created a Server on my Local Computer (Worked like a charm)
-Reinstalled my friends Minecraft client (tried MS Store and Installer)
-My Friend Re-Booted and Re-Logged
-Used my Public IP Instead of Domain
-Checked Firewall Logs (temporarily opened completely → did not help)

Not an AMP issue. If it works with some users but not others it’s stricly handled by Microsoft. AMP is entirely uninvolved with anything that happens in-game or anything to do with the verification of users.

I can understand you standpoint.
But everything works from the side Mojang and/or Microsoft.
Only when I use AMP the server does not accept NEW players

I’ve now also confirmed that running a Minecraft server on the same server as AMP, does Work as expected.

EDIT:

Turns out, disabling “Disallow proxied connections” fixes the problem.
It works now but I’m curious on what basis AMP blocked all outside connections? :thinking:
Thanks in advance :grin:

AMP does not block anything. The “Disallow proxied connections” setting is part of the Minecraft server itself. Like I said, none of this is anything to do with AMP :slight_smile:
