ERR_TOO_MANY_REDIRECTS Nginx

Question

Я только что обновил свою подписку Let's Encrypt с помощью команды

sudo /usr/local/bin/certbot-auto --nginx

, что дало ошибку, которая была устранена путем удаления строки

# proxy_redirect http:// https://;

из / etc / nginx / sites- доступный / по умолчанию, который я думал, это хорошо, так как он все равно выглядит для меня как комментарий. Однако теперь мой веб-сайт больше не загружается и выдает ошибку

This page isn’t working 
example.com redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS

Я попытался добавить строку обратно, но это не помогло. Любые мысли о том, что могло пойти не так?

здесь мой / etc / nginx / sites-available / default

server {
    listen 80 default_server;

    server_name example.com www.example.com;

    return 301 https://$server_name$request_uri;

Problems found:
Too many redirects. Please try to reduce your number of redirects for https://www.benty-fields.com. Actually you use 19 Redirects. Ideally you should not use more than 3 Redirects in a redirect chain. More than 3 redirections will produce unnecessary load on your server and reduces speed, which ends up in bad user experience.
