Since November there are massive connection problems to the STO server when you connect from some europe countries and also some US states.
Cryptic was not very supportive so far so i came up with my own solution.
with the launcher you could select a new proxy server under the options
problem is that there are only 2 options available (EU and US) while cryptic actually has more proxies.
in the launcher you can also set a command line option.
there you can put e.g. "-SetProxy eu2.proxy.crypticstudios.com 80"
this one used to solve the lag problems for me (you might need to see which proxy is working best for you -> eu1, eu2, us1, us2... )
however... this solution requires you to connect to the game via launcher
but what is what the connection problems are so bad that not even the launcher is loading (yep that happend frequently in the past weeks)
I worked on a different approach.
Lets bypass the launcher and directly connect to the STO servers via proxy.
create a batch file with the following content and put that file into the same folder where the gameclient.exe is located (.\Star Trek Online\Live\).
"start /b GameClient.exe -Locale english -server 18.104.22.168 -server 22.214.171.124 -server 126.96.36.199 -server 188.8.131.52 -SetProxy eu2.proxy.crypticstudios.com 80 -enabledebugconsole -console"
you can edit the language in this command and also the proxy name
if you dont want to run the game console in background then remove the last 2 commands
run that batch file and it will start the game and connect you to the patchserver and the game server using the proxy
this way you can get into the game even when the normal connection to the sto server and its launcher is problematic
