yes all urls except whitelisted domains get blocked for everyone but support staff.

are you accessing via LAN it should only authenticate over my.jdownloader and switch to lan connection for communication after that. If everything else is over wan and then vpn it will increase latency vs direct connect from your installation to your client via my.jd servers.

jd <> vpn <> my.jd <> mobile device
jd <> vpn <> my.jd <> vpn <> mobile device
jd <> my.jd <> mobile device

the docker supporter does have information about setting up direct connection.

more vpn connections you have the slower and higher latency you'll experience.
