WebUI on Windows 10

[sandstrw]

Been using qBittorrent for a long while suddenly am unable to use the webUI on my local account(for Sonarr login). Message is: "WebUI configuration failed: Unable to bind to IP: localhost, port: 8080. Reason: Unknown error". I've tried different ports under different IP address configurations. Also tried a full uninstall / reinstall of qBittorrent, with no change, except that it worked on one of the reinstalls for about 5 minutes before erroring out.

Any suggestions on handling this?

Either put this to bind to all:

*

Or if you only want one interface, put that IP there.
If you don't want anyone on your LAN to reach it, simply use Windows Firewall and block the port from outside.

"*

was the original state when installed, and is where I had the issue to start with. It just suddenly started disallowing webui access.

Check if anything is using 8080 first: https://stackoverflow.com/questions/481 ... on-windows

For example:
- https://www.nirsoft.net/utils/cports.html
- https://learn.microsoft.com/en-us/sysin ... ds/tcpview
- netstat -aon | find "LISTENING" |find "8080"
- netstat -abno

You also have a bunch of sus apps running in the taskbar. Do you have anything else for ""security"" besides crapware bytes?

Checked and nothing using 8080, malwarebytes is running for VPN

After upgrading to qBittorrent 5.0, I encountered the same issue. Using ‘127.0.0.1’ instead of ‘localhost’ solved it.

Thanks, this solved the issue.
