Wow, after hours of searching I found out, that there is an error (??) in the behaviour of RM according to proxy servers.
I added proxy servers for the access to the internet to get updates and information and so on
(company firewall!!). As I tried to apply database connections I permanently failed, except I tried
to connect to a local database (which I had to install and configure in advance
).
So I removed all proxy configuration from RM (and had to restart since using a proxy or not seems to be
configured only at startup) and voila - all database connections worked properly.
Modified:
Now I have to decide whether I want to get update information or I want to apply database connections?!?!?!?!Is there a workaround?Solution:
Yes, there is a workaround (maybe the standard configuration??):
Configure
ftp.proxySet and
http.proxySet for the firewall and
NOT https.proxySet!!!
Then all is working properly!
