Meu certificado SSL expirou recentemente. Para renovar o certificado usei o certbot, mas agora o certificado será renovado automaticamente pela minha hospedagem. Mas antes que isso aconteça devo fazer o redirecionamento de http para https no servidor. Você pode me ajudar com isso?

Este erro ocorre no meu site (domukasi.pl):
ERR_TOO_MANY_REDIRECTS
Também não consigo reiniciar meu servidor nginx.

É estranho que você esteja recebendo um ERR_TOO_MANY_REDIRECTSerro no seu navegador, pois o seu nginxservidor não foi iniciado.
Parece que algum outro servidor já está escutando nas portas 80 e 443, o que está causando esses redirecionamentos e também falhando nginxna inicialização.
No log de erros você está recebendo
Aug 18 07:42:12 vps685363 nginx[27222]: nginx: [emerg] bind() to 0.0.0.0:443 fai
Aug 18 07:42:12 vps685363 nginx[27222]: nginx: [emerg] bind() to 0.0.0.0:80 fail
o que indica que nginxnão é possível vincular-se a essas portas, o que indica que elas já estão sendo usadas por outro processo ou que nginxnão possui privilégios suficientes para vincular-se a essas portas (já que estão abaixo de 1024). Acho que você já tem outro servidor rodando nesta máquina que está utilizando essas portas.
Você pode verificar se essas portas já estão sendo usadas emitindo
sudo lsof -i :80e
sudo lsof -i :443
ou
sudo netstat -ltnp | grep -w ':80'e
sudo netstat -ltnp | grep -w ':443'
