OpenProject Installed using Docker - Problem with Nginx: Redireted too many times - docker

Question

I have hit a wall trying to fix a problem with my openProject installation. I installed it following the instructions in this guide. Then, I added an A record for my public IP and subdomain using world4you. I also created SSL certificates with Let's Encrypt:
mkdir /var/www/certbot/openproject.invert.at
certbot certonly --webroot -w /var/www/certbot/openproject.invert.at -d openproject.invert.at
Then I created and modified a file named /etc/nginx/sites-enabled/openproject.eeg_invert.de as follows:
server {
listen 80;
listen [::]:80;
listen 443 ssl;
listen [::]:443 ssl;
# ssl_certificate /etc/letsencrypt/live/openproject.eeg_invert.de/fullchain.pem;
# ssl_certificate_key /etc/letsencrypt/live/openproject.eeg_invert.de/privkey.pem;
access_log /var/log/nginx/access_openproject.eeg_invert.de.log;
error_log /var/log/nginx/error_openproject.eeg_invert.de.log;
server_name openproject.eeg_invert.de;
if ($http_user_agent ~* ".*SemrushBot.*") {return 403;}
location '/.well-known/acme-challenge' {
root /var/www/certbot/openproject.eeg_invert.de;
}
location / {
if ($scheme = http) {
return 301 https://$server_name$request_uri;
}
proxy_set_header X-Script-Name /;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Remote-User $remote_user;
proxy_set_header Host $http_host;
# proxy_redirect http:// https://;
proxy_pass http://localhost:8080;
}
}
I reloaded nginx and everything worked just fine. However, I updated this application using cd /docker/openproject/compose && docker-compose pull && docker-compose up -d and reloaded nginx but now I am getting this message on chrome:
This page isn’t working openproject.eeg_invert.de redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS
I backed up all relevant docker volumes and the entire project folder (where the compose file is located) before updating. I am in no way an expert in IT so what I did so far is to run docker-compose down after updating. Then I restored the project folder and ran docker-compose up -d.
The problem is that now I am still getting the same error. I looked at the nginx error log files, but nothing comes up. I tried disabling some of the options at random from the nginx files to see if that changes something but it is always the same.
I have hit a wall now and I would very much appreciate your help! Thanks in advance for any suggestions or ideas you may have.

Did you try clearing cookies in your browser? There are many reasons why this issue can occur:
Issues with the browser's cache/cookies. The browser may be caching faulty data that leads to the redirection error.
The browser extensions. Sometimes a browser extension can cause a redirection error.
The website's URL. A misconfiguration in URL settings can cause the redirection error.
WordPress cache. The website cache could be causing a redirect loop.
SSL certificate. A misconfigured security protocol (SSL certificate) can cause a redirect loop.
Third-party services and plugins. A faulty WordPress plugin could be causing the redirection loop.
The site's .htaccess file. A user-level configuration file WordPress uses to rewrite URLs to the index.php file. The website URL is defined as a value in the database.
