The error more or less tells me the ASP application has issues fetching its URL. Can I somehow convince Nginx to work around this issue? The IIS server is a blackbox, no modifications can be made there. My stracktrace:

Probably you need

location / {
     proxy_pass  http://theproxiedserver/somepath;
     proxy_set_header   Host   thepublicservername;
     # or
     proxy_set_header   Host   $host;
}
