Using a proxy server

If you do not know if you have to use a proxy server and you get “Login failed: already connected” as error message when trying to log in then that’s most likely the indication for it.

  • When the program has started, click on the home menu button on the top left and select “Proxy settings…”. In the following dialog you can set the proxy host, port, user name (optional) and password (optional). This is the recommended method for using a proxy server.
  • Alternatively, you can edit the start script (e.g. Transkribus.bat on Windows, on Linux) to include the environment variables for the proxy server:

java -Dhttps.proxyHost=




-jar Transkribus-0.7.0.jar

However, editing this file will be necessary on each update of Transkribus.
