Hi,
I have a problem with port 80. It seems to me that digitalocean blocks port 80 (I could not access port 80 even when firewall was switched off)
Here is what I already did:
root@XXXXX:~# iptables -L
Chain INPUT (policy DROP)
target prot opt source destination
ACCEPT all – anywhere anywhere state RELATED,ESTABLISHED
DROP all – anywhere anywhere state INVALID
ACCEPT all – anywhere anywhere ;
ACCEPT tcp – anywhere anywhere tcp dpt:ssh
ACCEPT udp – anywhere anywhere udp dpt:ssh
ACCEPT tcp – anywhere anywhere tcp dpt:http
ACCEPT tcp – anywhere anywhere tcp dpt:8030
ACCEPT &nb sp; icmp – anywhere anywhere icmp echo-request
REJECT tcp – anywhere anywhere state NEW tcpflags:! SYN,RST,ACK/SYN reject-with tcp-reset
REJECT tcp – anywhere anywhere tcpflags: SYN,RST,ACK/SYN reject-with tcp-reset
REJECT tcp – anywhere anywhere tcpflags: FIN,SYN,RST,PSH,A CK,URG/FIN,SYN,RST,PSH,ACK,URG reject-with tcp-reset
REJECT tcp – anywhere anywhere tcpflags: FIN,SYN,RST,PSH,ACK,URG/NONE reject-with tcp-reset
REJECT tcp – anywhere anywhere tcpflags: FIN,SYN/FIN,SYN reject-with tcp-reset
REJECT tcp – anywhere anywhere tcpflags: SYN,RST/SYN,RST reject-with tcp-reset
REJECT tcp – anywhere ; anywhere tcpflags: FIN,SYN,RST,PSH,ACK,URG/FIN,SYN,RST,ACK,URG reject-with tcp-reset
REJECT tcp – anywhere anywhere tcpflags: FIN,SYN,RST,PSH,ACK,URG/FIN,PSH,URG reject-with tcp-reset
REJECT tcp – anywhere anywhere reject-with tcp-reset
DROP all – anywhere anywhere
Chain FORWARD (policy ACCEPT) target p rot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all – anywhere anywhere

We definitely do not block port 80, or any other port. Try clearing your firewall rules: <br><pre>iptables-save > /root/iptables_backup-“$(date)” <br>iptables -F <br>iptables -X</pre>
