I am getting ERR_TOO_MANY_REDIRECTS after installed Let's Encrypt. Please help.

When visiting your site I did not see this issue occur. When setting up LetsEncrypt a redirect may be set up to force users visiting the http version of your site to be redirected to the https version. If you are running a platform like WordPress you can end up with dueling redirects. WordPress will automatically redirect to the configured URL. If you configured your site over http this could cause WordPress to try and redirect https traffic back to it’s configured http address. These two redirects together could then combine to create an endless loop of redirects resulting in the error you are seeing. The easiest way to fix this would be to update the configured URL in WordPress (wp-admin) to use the https version of the site.
