Too many redirects on certificate renewal

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: my.immerseme.co

I ran this command: ./certbot-auto

It produced this output: IMPORTANT NOTES:

  • Congratulations! Your certificate and chain have been saved at:
    /etc/letsencrypt/live/my.immerseme.co/fullchain.pem
    Your key file has been saved at:
    /etc/letsencrypt/live/my.immerseme.co/privkey.pem
    Your cert will expire on 2020-08-04. To obtain a new or tweaked
    version of this certificate in the future, simply run certbot-auto
    again with the “certonly” option. To non-interactively renew all
    of your certificates, run “certbot-auto renew”

My web server is (include version): Cloudflare

The operating system my web server runs on is (include version): Linux Ubuntu

My hosting provider, if applicable, is: Cloudflare?

I can login to a root shell on my machine (yes or no, or I don’t know): Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.31.0

After running this command the site was working well and I thought I had renewed the existing certificate. I found a couple of hours later the site was down and we had this error displayed:

This page isn’t working

my.immerseme.co redirected you too many times.

ERR_TOO_MANY_REDIRECTS

Any help would be so highly appreciated, fixing this issue is really urgent, we have thousands of new users waiting to use the site.

Hi @tomasbrown

then check your domain with "check your website", then you should see, if you have a http -> https -> http redirect or a https -> https. Then fix it.

Hi @JuergenAuer

The result I got from Redirect-checker.org is:

I am new to this so unsure how to fix an https -> https error, do you have any advice on where this may originate from?

Now there is a check of your domain - https://check-your-website.server-daten.de/?q=my.immerseme.co

Grade B, no loop.

Looks like you have found and removed that wrong redirect https -> https. :+1:
