I just setup HTTPS on my local agent by following the docs. Everything is functioning as expected.
When looking on the "Default Web Site" in IIS I get an alert saying:
No default SSL site has been created. To support browsers without SNI capabilities, it is recommended to create a default SSL site.
I understand this mostly impacts old browsers, but I wonder if this will impact any DataMiner functionality.
Aside from very old browsers not being able to reach the website (all major browsers have had SNI support for quite some time now), I'm not expecting further issues with DataMiner functionality or at least haven't seen any so far related to this. The warning here can most likely be safely ignored.
If this would turn out to be an issue after all, it should be possible to resolve the issue by unchecking the "Require Server Name Indication" checkbox for one of the HTTPS binding configurations. (also see here)
Thank you for confirming this!
