Windows 8.1, IIS 8.5. The laptop, which was used as the main machine for development for a long time, has now become a "vacation option", I take it on trips and everything worked before, there was no described problem.
The problem is the following: when you open localhost in the browser, there is an endless download. The browser writes "Waiting for a localhost response" and nothing happens, not after a minute, not after ten, not after another interval. Doesn't give any errors.
I tried to request existing and non-existent pages - also eternal loading.
Tried telnet localhost 80, then GET anything - nothing, blank screen, waiting for a response. If you send not a GET but an invalid request, then it gives a response like

I tried: rebooting, reinstalling IIS, installing all the components that are in IIS - nothing helped.
Logs are enabled, but the logs folder is empty. Found logs in C:\Windows\System32\Logfiles\HTTPERR
But the content is strange - almost all my queries are missing

I noticed that when the iisreset /restart service is restarted, entries appear in the logs that the current open connections (those pages that I try to open and which do not open) are dropped.

Honestly, it's not clear what you mean, but what if you wrap the picture with a block to which you specify the height, and set the picture to 100% height, have you tried it?
