HTTPS Reverse Proxy on IIS 10 – External Access Fails (Timeout) Although Local Requests Work
Hello everyone, I’m currently facing an issue with an IIS 10 reverse proxy configuration on Windows Server, and I would really appreciate your guidance. Environment Windows Server IIS 10 Application Request Routing (ARR) + URL Rewrite enabled Backend application running on: http://localhost:8080/ http://localhost:8080/login Public domain: https://lojistik.abc.com.tr What I want to achieve I want users to access the backend web application through the following URL: https://lojistik.abc.com.tr/LMYS/login Internally, IIS should proxy this to: http://localhost:8080/login What works The backend application is accessible without issues: http://localhost:8080/login From the server itself, reverse proxy works: Invoke-WebRequest "https://lojistik.abc.com.tr/LMYS/login" → StatusCode: 200 (success) What does NOT work From any client machine, the following request results in a timeout: https://lojistik.abc.com.tr/LMYS/login Browser shows connection timeout. No entry appears in IIS logs for external requests to /LMYS/.... Tests performed ▪ netstat -ano | findstr :443 on the server → Port 443 is listening ▪ DNS resolves correctly: lojistik.abc.com.tr → 10.6.130.90 ▪ Reverse proxy rule on IIS is correctly configured under the HTTPS binding site: Pattern: ^LMYS(/.*)?$ Rewrite to: http://localhost:8080{R:1} ▪ ARR Server Proxy is enabled. Key observation Requests from the server itself succeed (reverse proxy returns 200), but external clients always time out, which suggests that the HTTPS traffic is not reaching IIS at all (likely blocked or not NAT-forwarded on the network path). Question What could cause HTTPS (port 443) traffic to reach IIS locally, but external requests to the same port to hang indefinitely? Any guidance would be greatly appreciated. Thank you in advance. Best regards,using IIS URL Rewrite module for HTTP to HTTPS
I have installed the URL Rewrite module in IIS 10 to redirect HTTP calls to HTTPS, and I have attempted to set up the redirect but have not gotten it working on one server. Here is the issue: Server1 with IP 1.1.1.1 is running IIS with an https enabled website. An outside DNS has assigned https://gohere.com to IP 1.1.1.1. When users attempt to get to http://gohere.com the connection times out and it is not redirected to https://gohere.com Accessing https://gohere.com works without an issue. Here is the rewrite code from the web.config file. <rewrite> <rules> <rule name="HTTP to HTTPS" patternSyntax="Wildcard" stopProcessing="true"> <match url="http://gohere.com*" /> <conditions> <add input="{HTTPS}" pattern="^OFF$" /> </conditions> <action type="Redirect" url="https://gohere.com" appendQueryString="false" /> </rule> </rules> </rewrite> I have also tried using match url=".*" Any ideas on what might be causing the issue? Or something to try to get it working? Thanks! Jim
Logging API HTTPS URIs
Hello I run a local Java applet which opens a SunAwtFrame window and I click a button there to download a csv. I want to see the URI of this download as it should be a permanent link as part of an API. The problem is that it is under HTTPS, certificates and perhaps via localhost. Is there a way to get that URI? Thanks!
IIS 10: how to enable both HTTPS+HTTP bindings on one site to access the site from internet or local
Hi, I run an IIS web site having HTTPS binding for host name = "opendata.sperling.cz " at port 443. It is accesible from internet, as the name is revorderd in DNS and tehre is a rule in our router's firewall to reach the site. This is fine. What I would like achieve is to be able to acces the site from local network or even localhost using HTTP port. I have added a binding without any host name using port 91, but it doesnot work. I have tried to access it via http://localhost:91/ or http://192.168.10.20:91/, but non of it worked. It always redirected to https://localhost and disaplayed an SSL error, as the HTTPS host name does not match the entered. What is wrong? Is it even possible? Thanks.

First published on MSDN on Apr 28, 2017 While helping customers troubleshooting HTTP-related error, a common question that we face: What is Timer_ConnectionIdle (as we see a lot of them in the HTTPERR log)?, and is this something to worry about?Here is an excerpts from the HTTPERR log:2016-07-05 18:45:09 172.
