how to fix ERR_CONNECTION_RESET

Hi @Kenyon Papaj ,

Thanks for sharing your details!

From my understanding, ERR_CONNECTION_RESET means the connection is being cut off before the page can load.

When this happens, the first thing to confirm is whether the server is still able to accept connections. If this server is running IIS, please check that the World Wide Web Publishing Service (W3SVC) is running, and that the website and its application pool are both started in IIS Manager.

If everything looks normal in IIS, the next thing to check is whether anything around the server is blocking traffic, such as firewall rules or network security settings. These can stop connections before they ever reach the website.

If you want a simple explanation of what this error means and some basic things to double‑check, this article walks through it clearly:

Once you’ve checked whether the server is accepting connections and whether traffic is allowed through, we can narrow it down further based on what you find.

Hello,

Probably, if you are trying to visit the website by IP address, it does not have an SSL certificate, and if you are trying to visit the website with a secure connection (HTTPS), it will show this error. Instead, use HTTP (or setup domain & SSL certificate)

Are the services running? Make sure the W3SVC (World Wide Web Publishing Service) service is running in services.msc. Also, check that your site and application pool are in the "Started" state in IIS Manager.

If the problem isn't with IIS, you can reset your network settings, which often helps with connection errors.

Run the following commands one by one:

batch
netsh winsock reset
netsh int ip reset
ipconfig /flushdns

Sometimes the problem can be caused by the cache or browser extensions.

Try opening your server in incognito mode.

If everything works there, clear your browser's cache and cookies for the entire time.

Also, try checking Windows Updates (after searching the internet, I noticed that this helps someone)
