Forge (Any) "Failed to verify username"

[Erika404]

Error occurs when trying to connect to any server

Failures occurs on CurseForge as well as manual forge-mod installations

Forge Versions that have failed for the past many hours

Minecraft 1.18.2

forge-40.2.0

forge-40.1.93

forge-40.1.92

forge-40.1.87

forge-40.1.86

forge-40.1.85

Error does not occur on the Vanilla Minecraft launcher and server connections on

Vanilla 1.18.2

Vanilla 1.18

Vanilla 1.19.3

Vanilla 1.19

I have tried with 2 Minecraft accounts

1 (One) New (Bought today due to this error)

1 (One) Old (Migrated from Mojang)

Programs have been removed and reinstalled multiple times.

A complete PC wipe has also been done, no changes.

 

I am lost, I don't know why it occurs or how to fix it. 

 

Any suggestions on solutions would really be appreciated.

 

Edit: 

Thought I should add this, no information shows on the server-side of things since the account doesn't get a chance connect, nor does the game crash in any way.

Added no crashing or connection actually occurs

Try add this to your java args "-Djava.net.preferIPv4Stack=true"
This worked for a member of my server.
