[Share]Cannot access IIS/FTP from outside

I have a ECS Windows instance setup for and running Microsoft IIS server and FTP server.  But when I try to access the website from anywhere other than localhost (from a browser outside of the Aliyun cloud), I get the ERR_CONNETION_REFUSED error.  The firewall is setup to allow HTTP traffic.  Similiarly for ftp, I cannot make a connection to the ftp server.  Is TCP traffic to the instance being blocked somewhere?


Thanks.

netsh http delete iplisten ipaddress=127.0.0.1

netsh http add iplisten ipaddress=0.0.0.0

It could be blocked by the security group, please check the rules. According to your description, you can fix the issue by using either of the way provided below:
1> Edit the security group rules, open the ports of ftp and http server to the ECS server that you want them be able to access the server.
2> Grant the same security group to both the server and clients.
