Hi Jess
I checked and reconfigured with a chain certificate.
It seems the problem was the missing chain cert.
Thank you.
The ouput was:
curl -I -v https://mydomain.ch
* Rebuilt URL to: https://mydomain.ch/
* Hostname was NOT found in DNS cache
* Trying 10.0.251.87...
* Connected to tube.htwchur.ch (10.0.251.87) port 443 (#0)
* successfully set certificate verify locations:
* CAfile: none
CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* SSLv3, TLS handshake, Server hello (2):
* SSLv3, TLS handshake, CERT (11):
* SSLv3, TLS alert, Server hello (2):
* SSL certificate problem: unable to get local issuer certificate
* Closing connection 0
* SSLv3, TLS alert, Client hello (1):
curl: (60) SSL certificate problem: unable to get local issuer certificate

curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
