Just updated our install to 1.17 and also using PHP 8.1.11 as needed on IIS running Server 2019 hosted internally. Having to do the update so we can sort out OAuth2 for fetching e-mails as Microsoft have just 'upgraded' our tenant to remove basic authentication.
Problem is now, I can't log in to the scp. Just reverts back to Authentication Required. However, I noticed if I use the internal IP address of the server, then I can log in with my credentials which uses LDAP Plugin (with TLS) to authenticate against our Domain Server(s).
Points to a DNS issue (doesn't it always?), but from what I can see everything looks in order with the setup of the server, DNS entries, etc. And this setup worked quite happily before I did the upgrade.
Out of frustration, I built a new server running Server 2022, all freshly installed with IIS, MySQL 5.5, PHP 8.1.11, etc and all installed fine, but again, using LDAP authentication works using the IP address, but not the hostname of the server.
Appreciate any help on this one. Many thanks.
Pete
