Actually in the PC hosting the Web Server I have Ubuntu 18.04.01 Server Edition.
For browsing in internet and for connecting via ssh to the PC I use a Windows 10 laptop. But does it affect the PC hosting the web page? It shouldn’t.
These are the DNS settings of my Domain : DomainDNSSettings
Now I disabled :
- the Karspersky Internet Security Firewall of my laptop:
- the overall Windows Defender Firewall of my laptop:
But unfortunately again, refreshing or connecting with https://check-your-website.server-daten.de/?q=ggc.world it says:
“ConnectFailure - Unable to connect to the remote server No connection could be made because the target machine actively refused it 188.8.131.52:80”
and doing :
sudo certbot certonly --webroot -w /home/marco/go/src/MyPage/ -d ggc.world -d www.ggc.world
I got the same error message as above
even if I do not understand what it could interfere with the Internet Service Provider’s Security Configurations
