I have a yaws webserver. I'm trying to connect via https in local network. When I setup my server in yaws.conf for http, as follows, all works fine when I connect via http://0.0.0.0:80/myappmod in browser
<server *:80>
port = 80
listen = 0.0.0.0
docroot = /home/anyuser/anydir/
auth_log = true
appmods = </, myappmod>
</server>
But the following config (with ssl) does not: (I connect via https://0.0.0.0:443/myappmod)
<server mydomain.com>
port = 443
docroot = /home/anyuser/anydir/
listen = 0.0.0.0
dir_listings = true
auth_log = true
appmods = </, myappmod>
<ssl>
keyfile = /home/anyuser/private-key.pem
certfile = /home/anyuser/cert_by_ca.pem
depth = 0
</ssl>
</server>
The certificate is officially issued by certificate authority and generally works for other webservers under "mydomain.com". private-key format is this
-----BEGIN PRIVATE KEY-----
MIIEvQIBADANBgkqhkiG9w0BAQEFAASCBKcwggSjAgEAAoIBAQC7WBJR0YV9bq4P
...
CAy+LaJpyW/b2vQ+He7t/rg=
-----END PRIVATE KEY-----
And .crt file is of this format:
-----BEGIN CERTIFICATE-----
MIIGgjCCBWqgAwIBAgIIZiCEI/Q/x7gwDQYJKoZIhvcNAQELBQAwgbQxCzAJBgNV
...
1CtNn+5v4lBpgzWS0ZSv5xkeskHjzXnRbjl7jzbkwUdseCZHwXc=
-----END CERTIFICATE-----
When I'm trying to connect, I get ERR_CONNECTION_RESET in Chrome and PR_END_OF_FILE_ERROR in firefox. What am I doing wrong? I can't find any more infos on the config in the official yaws docs. Can someone help please?

EDIT2: Die Verbindung wurde vom Kommunikationspartner zurückgesetzt means: The connection was reset by the communication partner in English.
Is the decode error (562) due to invalid cert-file encoding? I must admid, that I got 2 files from godaddy.com: One .pem and one .crt file. Their contents looked identically to me. Content is as posted above.(I used the .pem file in yaws.conf). The key-file I am using is the output I copied from the cert sign request on godaddy.com. (Just copied it from their Web-TextBox and pasted it into a .txt file on ubuntu).
EDIT3:
openssl s_client -connect mydomain.com:443 (dns works for http//mydomain.de:80) gives me:
CONNECTED(00000003)
write:errno=104

EDIT4:
So I produced some more output. First I verified, that my certificate is ok. Therefore I made an openssl-client and server the following way:
openssl s_server -accept 8443 -cert /etc/mydomain.pem -key /etc/mydomain.key -CAfile /etc/gd_bundle-g2-g1.crt
openssl s_client -connect localhost:8443 -cert /etc/mydomain.pem -key /etc/mydomain.key -CAfile /etc/gd_bundle-g2-g1.crt -verify 8 -verify_hostname mydomain.de
Which results in a successful handshake:
... Certificate and other data I do not want to post and:
SSL handshake has read 5658 bytes and written 373 bytes
Verification: OK
Verified peername: mydomain.de
... more data
Then I setup one http and one http server using the following config file. I further assured .pem and .key file can be accessible by yaws with chmod +777 (I know this is bad but I just wanted to be sure). Then I started the yaws server (with root priviliges, which I know is evil too, but until I figured out how to bind to priviliged ports as non-root, I go with that just for testing)
logdir = /var/log/yaws
ebin_dir = /usr/local/lib/yaws-appmods/ebin
include_dir = /usr/local/lib/yaws-appmods/include
max_connections = nolimit
keepalive_maxuses = nolimit
process_options = "[]"
acceptor_pool_size = 8
trace = false
use_old_ssl = false
copy_error_log = true
log_wrap_size = 0
log_resolve_hostname = false
fail_on_bind_err = true
pick_first_virthost_on_nomatch = false
keepalive_timeout = 30000
sni = enable
<server mydomain.de>
port = 80
listen = 192.168.178.75
docroot = /home/my_non_root_user/my_appmod/
auth_log = true
appmods = </, my_appmod>
</server>
<server mydomain.de>
port = 443
docroot = /home/my_non_root_user/my_appmod/
listen = 192.168.178.75
dir_listings = true
auth_log = true
appmods = </, my_appmod>
<ssl>
keyfile = /etc/mydomain.key
certfile = /etc/mydomain.pem
depth = 0
</ssl>
</server>
I also tried providing the ca-bundle, setting higher depths, and played with some other parameters, but all to no success. I got the same error as described above. In the following yaws output, one only can see that http is working. When I try to connect via https, there is no output produced. No worker, etc. I am very new to yaws and webservers in general. I like erlang very much, and just wanted to have a small webserver for my own. No production ready, sophisticated solution. I guess I did something wrong in my config file or have just incomplete knowledge about the whole webserver concept.
