Ahoj, něco jsem našel na R* foru. Můžeš vyzkoušet. :)

Hey! I found how to fix this problem (at least in my case). I had the same error (on win7). this is what i did: Open start menu -> type in: proxy -> Configure proxy server -> click LAN settings on connections tab -> tick Use a proxy server for your LAN box -> click OK -> click OK again -> try to run GTA V. I hope this will help!!

Hey Guys I have found a fix for (202) Error. So the first thing to do is Click on the Start Button, Type cmd, then press Right Click and Press "Run as administrator". When the administrator tab is open Press Yes. Then when you are in type " ipconfig/flushdns" . Then it must say " Windows IP Configuration. Successfully flushed the DNS Rosolver Cache". Okay when this is done, type the following "netsh winsock reset". And Yes with the Space. From then it must say "Successfully reset the Winsock Catalog. You must restart he computer in order to complete the reset".
I hope this helps.
