How do I renew a certificate with lego?

[Sgtkeebs]

Hello,

To create a certificate this is the command that I used:

DOMAIN_NAME=mydomain \
EMAIL=myemail \
DNS_PROVIDER="godaddy" \ 
GODADDY_API_KEY="my api key" \
GODADDY_API_SECRET="my api secret" \
./lego.sh 

When I run this command, it reaches out to https://github.com/go-acme/lego/releases/download/v4.14.2/lego_v4.14.2_linux_arm64.tar.gz and downloads the tar.gz and runs the script to create my crt and key files.

When I go to renew running this command:

/opt/lego/lego --email="[email protected]" --domains="example.com" --http renew

I recieve this error:

2024/01/01 00:00:43 Account [email protected] is not registered. Use 'run' to register a new account.

Using the run command, I receive this error:

HTTP server for challenge: listen tcp :80: bind: address already in use

I have two working .crt and .key files from the first command. My certificate was about to expire so I had to run the first command again to get around this error. How do I properly renew my certificate?

Edit: It looks like I got lego.sh script from https://github.com/ameshkov/legoagh so I am unsure if you all can help?
