OnPrem Director 2507 CU1, Server 2025. net new environment. can't log into Director. I can point Director to legacy 2203 site and it works but not to this one new DDC. WebStudio (legacy console) works fine, same issue using https://localhost on Director server or FQDN across other endpoints. I can tnc from Director to DDC on ports 80,443 just fine. Anyone run into this? I did try https://support.citrix.com/external/article/CTX206380/cannot-log-on-to-citrix-director-no-sit.html with no luck.

used to be a bug where Service.AutoDiscoveryAddresse in Director IIS settings used to be blank or set to localhost which used to cause issues. Set it to FQDN

Yeah. Tried IP, hostname and FQDN with no luck.
