Is there a way to see what the IIS 8.5 server does when I access a site via HTTPS from an external network? What does it open, what folder structure, which file?
I'm asking this because when I access my sites via HTTPS from external I always get redirected to the IIS Default Page, even though I stopped the default web site in IIS and deleted all html-files which are in inetpub/wwwroot by default. When I access HTTPS from internal, everything works and If I access the site via HTTP no matter if internal or external, everything works.
Is there a way to see what the server does? Can I log something or trace something? The Logs I see right now don't give me any information to why it does not work.
It's so strange. when I open the site via HTTPS from external it opens this: https://mysite.mydomain.com/iis-85.png when I want to open this exact URL from internal network i get an
404 - File or Folder not found error. the only Folder on the whole IIS which contains this iis-85.png is this one:
C:\Windows\WinSxS\amd64_microsoft-windows-iis-startserver_31bf3856ad364e35_6.3.9600.16384_none_bf87a3597b95c1cd and I don't think it could possibly read the data from there.
why is this? Could it be that this is still cached? I did everything to renew the cache, deleted temporpy asp-files, flushed the dns, restartet every site, the IIS itself, every apppool. What else could I do?
Edit: OK I got it. HTTPS was redirected to another server via Firewall NAT.
