[SOLVED] Error in network behaviour with proxy server

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!

I had the same problem too. To be sure of completely removing all Proxy information I removed the "5_2_000_rapidminerrc.Windows XP" config file completely from my installation and restarted RapidMiner.

Interestingly, connections to local and remote MySQL servers were not affected by the Proxy config, only those to a remote Microsoft SQL server.
