Unable to connect to server

When I try to connect to the server i am getting the following generic errors:
Error Code: INET_E_DOWNLOAD_FAILURE from IE
ERR_CONNECTION_CLOSED from Chrome
it looks like it is not able to get a secure connection, when i disable the yunohost firewall it seems to connect fine.

I am using a hosted VPS from a provider and this is not hosted at home, I have provided a copy of the firewall settings from system.

I have tried from IE, edge, chrome and firefox and still cannot get access. I have scanned the computers for viruses and nothing.

Hi @rdixon0703

How do you “disable the yunohost firewall” ?

Do you have an SSH access ?

Can you look at tail -f /var/log/syslog ? or tail -f /var/log/fail2ban.log ?
