Renewal failure - cannot bind to port

that's my friend website made by a dev compagny, so i don't know all of the thing on it ^^

Someone followed some instructions to get a cert like 90 days ago.
Some of those instructions may be needed now.

i reboot the entire server but now it's completly down

the people who developed the site and you are not nice and left after the money

HTTP is still responding:

curl -Iki https://ohward.com
curl: (7) Failed to connect to ohward.com port 443: Connection refused

Did you just say that "I'm not nice"?
Please clarify your statement:

sorry google transalte ^^ not you

EXPRESS appears to be a NODE.JS (Java Script) application.

I'm not familiar with it.

since the creation of the site we have more contact with the developers

I don't know how to turn it on.

What is the user those commands are from?

Seems the command to start your express server is (executed from the home directory of the user):

sudo ng serve --port 443 --host 0.0.0.0 --ssl true --ssl-cert ../fullchain.pem --ssl-key ../privkey.pem --disableHostCheck

And also seems they are copying the fullchain.pem and privkey.pem files to that directory instead of using directly the entire path to the right files, instead of use the above command maybe you should use this command to start the express server and use the renewed certificates:

sudo ng serve --port 443 --host 0.0.0.0 --ssl true --ssl-cert /etc/letsencrypt/live/ohward.com/fullchain.pem --ssl-key /etc/letsencrypt/live/ohward.com/privkey.pem --disableHostCheck

Give it a try.
