mSigna for Litecoin - remote litecoin node

[opr1]

Hello,
Please could someone explain me how to synchronize with the blockchain? A few months ago I set Network settings to some Host and Port from here https://bitinfocharts.com/litecoin/nodes-active/czech-republic/prague.html and it worked. But now I am not able to find active litecoin node address (Host and Port). Page https://bitinfocharts.com/litecoin is accessible but when I click on country e.g. https://bitinfocharts.com/bitcoin/nodes-active/germany/ page is dead. Page https://www.litenodes.net/search?q=Germany contains many ?non?-active Hosts+Ports, and it do not work in mSigna wallett (rotating orange icon and note: connection error). Am I doing something wrong? How can I connect to the network? I am using last version of the wallett. Thank You in advance for your reply. O.
