Certbot can't access port 80

I am sure this has been covered a million times, but every solution I have seen doesn't work in my case. I am having an issue with getting certbot to issue a renewal license. The issue is port 80.

I am running a windows server 2016 standard VM. When I use cmd to run "certbot renew" I get the standard "Problem binding to port 80: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions"

It is set up as a remote desktop gateway. The program listening on the port is PID 4 SYSTEM or in other words HTTP services. I can't stop them however, because that is what allows the traffic to come from the URL "remote.cinnamonhills.org"

When I disable them to free up port 80 I get an error that the process timed out:

Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Domain: remote.cinnamonhills.org
Type: connection
Detail: Fetching http://remote.cinnamonhills.org/.well-known/acme-challenge/6CmwaRbHPaBguwhotYV9sK5H5s0EhKCFrhRufS4LCB0: Timeout during connect (likely firewall problem)

Its not a firewall problem as we have done this already a few times. I am at my wits end and cant figure out why it all the sudden failed. I was not with the company the last time it was done, but I followed their notes and it doesn't seem to work.

I am sure I left out several vital details, but any help would be appreciated.

The version of my certbot client is 1.22.0

Have you been using certbot or are you just starting?


That is what they used last time.

Something must have changed:

curl -Ii
curl: (56) Recv failure: Connection reset by peer
