After having installed a new TOS version (6.1.1) and starting TOS a registration window pops up. Trying to connect to my existing Talend account I get the error message "Malformed reply from SOCKS server". What could be the cause of this error? - Hint: I have to use a proxy. At least the settings for http and https work (yes - here https uses port 8080 and not the standard port 443). What is necessary on the proxy/firewall side for SOCKS requests?
