Redmine

I have bitnami redmine installed and am trying to connect to a remote server using curl using the built in terminal.

But it seems instead of using the remote server's certificate, it always loads some local cert file leading to an error no alternative subject name matches target host name xxx.

When I'm issuing this: openssl s_client -connect www.google.com:443 | openssl x509 -text -noout

I'm getting the certificate (letsencrypt) of my redmine-host as well.

The (partial) output of the openssl-command looks like this:

depth=2 C = US, O = Internet Security Research Group, CN = ISRG Root X1
verify return:1
depth=1 C = US, O = Let's Encrypt, CN = R3
verify return:1
depth=0 CN = my.localserver.com
verify return:1
Certificate: …

So the CN doesn't use google.com, but again the name of my redmine server.

When I look at the /etc/ssl/certs/ca-certificates.crt file, it seems that there are quite a lot in there. Alas, it always seems to select the cert for the local redmine host.

The problem with this is, that we are using the invoice module and have the logo that should be printed on the invoices (as well as a QR-Code for the ESR) are hosted on external servers. But because of the SSL problem, we get an error (server not found) in the invoice module when we try to create a PDF from within the module.

Any ideas what I'm doing wrong?
