I’m trying to install a react app on my CyberPanel control panel. So, I’ve created a subdomain and installed a React App on it. I’ve completed all the steps and the react app using the pm2 server is online now. but when I visit that subdomain it shows “431 Request Header Fields Too Large”. How do we resolve this error?
My configurations are given below:
- App Type: React
- npm, pm2 is required and installed.
- pm2 running on port 3030
I’ve added these lines to vHost Conf:
extprocessor ezcart {
type proxy
address 127.0.0.1:3030
maxConns 100
pcKeepAliveTimeout 60
initTimeout 60
retryTimeout 0
respBuffer 0
}
Rewrite Rules is configured this way:
RewriteEngine On
RewriteRule ^(.*)$ HTTP://ezcart/$1 [P]
I’ve tried these exact steps in a VPS and that’s working perfectly fine without any issues. However, I’m only finding this issue only with CyberPanel.
Can anyone please help me on this issue?
Thank you.
