Of course it could...

Yes, AtlantHarden changes several advanced Windows configurations that can restrict or break network connections. Because AtlantHarden acts as a persistent hardening utility rather than a background service, you cannot simply flip a toggle to turn it off. Instead, you need to manually reverse or reset the configurations it modifies. [1]

Settings Likely Breaking Your Network
AtlantHarden enforces strict security controls that frequently interfere with local networks, specific websites, and captive portals: [1]

• LOLBin Firewall Rules: It prevents common Windows binaries (like certutil, mshta, or wmic) from initiating network connections. If any of your applications rely on these system binaries for updates or data syncs, those connections will fail. [1]
• Strict Network & Protocol Restrictions: It enforces higher levels of authentication (SMB/LDAP signing, NTLMv2) and disables older protocols like TLS 1.0/1.1. If you are connecting to an older home NAS, office router, or legacy website, your connection will drop or be refused. [1]
• Aggressive Browser Hardening: It injects strict site-isolation policies, strict TLS enforcement, and rigid proxy or certificate validation. [1]

Turn it off and test...

It can't be simply turned off, it has various settings, I tried disabling crytography,tls, ssl related ones but still same
