Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My web server is (include version): IIS
The operating system my web server runs on is (include version): Windows Server 2019
My hosting provider, if applicable, is: Microsoft Azure
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot):1.8.0
I wanted to renew my Certificate. But it's showing me this Error:
" Problem binding to port 80: Could not bind to IPv4 or IPv6."
The Site is reachable via Port 80. I have no Idea where the problem can be. Maybe anybody of you have a Idea.
Thanks and Regards,
