[lamename]

I'm having React+Nodejs app on my server running globally via pm2. I wanted to use certbot in order to create ssl certificate.
My domain is 'somoontrans.ru'
I'm using VPS server and connecting to it via ssh. server by beget.
I have installed nginx and other needed stuff.
OS of vps server is ubuntu 22.04 LTS.

I tried to run certbot and got this error. (used this command ```
sudo apt install certbot python3-certbot-nginx

> Encountered exception during recovery: certbot.errors.MisconfigurationError: nginx restart failed:

Hi @lamename, and welcome to the LE community forum

@lamename

I'm having React+Nodejs
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Unknown error)

Which one is using port 80?
Show:
netstat -pant | grep -i listen | grep 80

[lamename]

Sure. It's 80 port.
I should run this command on my server?
i did it there.

tcp6       0      0 :::80                   :::*                    LISTEN      8862/node /root/cli```

[rg305]

That's not nginx on port 80.
[that's Node.js]

So, you shouldn't be using certbot with --nginx.

[lamename]

Can i use certbot --node or smth similar then?
Can't find it in official certbot documentation

[rg305]

No.
You could use certbot with certonly and use --webroot authentication.
