yehximin

Hi,

I have setup nodejs website on port 7500 and it started and running, but when visits "whatsapp.yelobee.com"

it gives "502 Bad Gateway - nginx"

here is what the website error log shows:

Hello, would you recommend checking whether the nodejs program is running? The log prompts that it cannot connect to port 7500.

Hi,
yes it is running fine:

aaPanel_Kern

Hello, it is recommended that you use the ssh tool or terminal execution command to check whether you can connect to the specified link.
curl -v http://127.0.0.1:7500/

yehximin

hi, I tried the command on the terminal, it says "connection refused"

yehximin

I tried other port (7800) but it gets "Recv failure: Connection reset by peer"

the server immediately crash for 7800 after started:

yehximin

anyone know how to fix this would really appreciate it

yehximin

is it possible that the firewall is blocking the ports?

aaPanel_Kern

It is recommended that you check what caused the automatic stop.

yehximin

do I need to create any IP rules/ port forwarding to make it work?
