Local and LAN systems talk, but will not authenticate

[SlayerOfSprites]

I’m looking for anyone to potentially help me here, really stuck…

Having some trouble getting any account to authenticate. Trying to set up 4 dedicated systems on a LAN that ultimately won’t be connected to the internet. The server runs and detects login attempts but will not authenticate any of the accounts. I have tried with virus scan and firewall off. I have tried both the community and test-stable builds. Followed all the steps and have tried various configurations in the ini file. Anyone have any idea what I am missing?

Have you tried turning off ipv6 in config?

Thanks for replying! Hmmm, just tried that and no luck. Also tried to disable IPv6 in the network adapter to see, but unfortunately that didn’t help either.
