What does the error message java.net.ConnectException (Connection timed out: connect) mean?
This means that the bank server does not respond within the given time interval.
The timeout for Connect und Read is set to two minutes by default, but can be configured in the BL Banking.ini file by adding the following lines.
Connect-timeout: -Dde.businesslogics.banking.timeout=<time in milliseconds>
Read-timeout: -Dde.businesslogics.banking.readTimeout=<time in milliseconds>
It should not be necessary to change the Connect-timeout, but for the Read-timeout it could be required to be able to retrieve very large files from the server. Sometimes the server needs more than two minutes to deliver a file.
