I have exactly the same problem. This is my first time with STO and I can't play since Saturday. I've submitted a ticket, hopefully it will get answered tomorrow.

In meantime i tried running game trough US/EU proxies, running a Safe login, verifying files, disabling/uninstalling Firewall (since i have to reinstall in anyway), changing configuration of my router, changing DNS servers to see if this will get me any better route to Cryptic servers ( i read somewhere that this was a problem at some point) all this with no positive results. I'm running out of options right now...

If only I would now what causes this maybe I could find some workaround...
STO logs shows
which is not very helpfully
