Failed to renew certificate fxw.systems with error: Problem binding to port 80: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions
My domain is: fxw.systems
I ran this command: certbot -renew
It produced this output: Failed to renew certificate fxw.systems with error: Problem binding to port 80: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions
My web server is (include version): nginx
The operating system my web server runs on is (include version): Windows
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 2.3.0
Certbot on Windows was never really a good idea, and is now deprecated--it's much better to use some Windows-native client for this purpose. But with that said, if certbot is trying to bind to port 80, that suggests it's being run in standalone mode, which doesn't seem appropriate if you're running a nginx web server.
If you're running ngnix that will hold onto port 80, if you're using certbot standalone you'd need to stop nginx and run certbot (as admin, with elevated privileges so you can use port 80).
So if you try that link yourself from a phone etc (external to your network) you should see that it fails to connect. Check that Windows firewall has TCP port 80 (http) open on the public network, if you are using a cloud VM host (e.g. Azure) also check the http (tcp port 80) is open in the network security settings in the cloud control panel for that VM.
