Failed to connect to example.com port 4000 Spree commerce-CodePudding

After installing Spree Commerce and running these commands, I am unable to access my domain http://example.com:4000/ or http://example.com:4000/admin.
When I run: curl example.com:4000 I got: curl: (7) Failed to connect to example.com port 4000 after 27 ms: Connection refused.
What is the reason I cannot access Spree Commerce on port 4:000 after fresh install and how can I correct this?

CodePudding user response：

There is no point for accessing - http://example.com:4000. As per the spree documentation, you should use http://localhost:4000 for accessing the spree application.

For Backend

For APIs

Hope this helps.

Firewall could be the principal problem. Have you tried checking opened ports?

List the current Iptables rules

sudo iptables -L

Add an Iptable rule (for example to open a Mysql port 3306)

sudo iptables -A INPUT -p tcp --dport 3306 -j ACCEPT

Remove an Iptable rule

sudo iptables -D INPUT -p tcp --dport xxxx -j ACCEPT
