I get the error "nginx: [emerg] unknown directive "tcp" in /etc/nginx/sites-enabled/...". Does it mean I configured it wrong or my installation of nginx didn't integrate this module properly?

Yes, I followed a tutorial on a blog. But before that I installed it with apt-get in ubuntu. I removed it and compiled it from the source with this module...

Thanks for your advise. There is nothing mentioned of this module in the configure arguments: nginx: nginx version: nginx/1.0.4 nginx: TLS SNI support enabled nginx: configure arguments: --prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log...

Thanks, it works great! But it's sad, that the same port does not work with tcp and http at the same time. Is there any workaround?

Okay, this might be a valid reason. But the scan of the QR code will show if it is valid without any further information of the vaccine. Name and birth-date...
