persistent connection problem on the Discovery server

[Faven95]

In the meantime, I also checked the Windows Security provider and firewall status on my system. ESET is the active antivirus and firewall provider, while Microsoft Defender and the Windows Firewall are disabled as expected in that setup, so there does not appear to be anything unusual on that side either. I have also ruled out the more obvious local causes as far as I reasonably can: I already did a completely clean reinstall of Discovery, set firewall permissions and exclusions in ESET, confirmed that DSAce.dll is present, tested with ESET disabled, and tested both through my normal home internet connection and separately through my mobile phone connection using USB tethering / hotspot internet, with exactly the same result in both cases. this no longer looks like a simple local installation, firewall, antivirus, single-character, account, or home-network problem on my side. At this point, could someone please check whether there is a server-side reason, an anti-cheat or client validation issue, or some kind of machine/client-related rejection that is causing this immediate post-login disconnect?
