Why is a symbolic link not being created on a relative path?

Question

linux

Broke symbolic links in letsencrypt. I decided to write a script that will fix this ... The problem is that broken links are created, and if you use the full let to the source, then everything works fine.

domain="example.com"
num="1"

rm -f ./live/$domain/*.pem
ln -s ./archive/${domain}/cert${num}.pem ./live/${domain}/cert.pem
ln -s ./archive/${domain}/chain${num}.pem ./live/${domain}/chain.pem
ln -s ./archive/${domain}/fullchain${num}.pem ./live/${domain}/fullchain.pem
ln -s ./archive/${domain}/privkey${num}.pem ./live/${domain}/privkey.pem

#проверку проходит!
FILE="./archive/${domain}/cert${num}.pem"
if [ -f $FILE ]; then
   echo "The file '$FILE' exists."
else
   echo "The file '$FILE' in not found."
fi

The relative path must be written relative to the link itself (sorry for the tautology), and not from the current directory.
For example, your link ./live/${domain}/cert.pem points to ./live/${domain}/archive/${domain}/cert${num}.pem
