I am currently experiencing issues with the Paradox launcher when I am trying to play Stellaris, this issue has only started happening about 3 days ago. I have reinstalled the game through steam, and have done everything suggested in the "Known issues and solutions" thread. I had tried reinstalling the launcher which I thought fixed it, only for it to break again the next day.
Any help would be appriciated.

In this folder are some .log files:
C:/users/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.
 
Sure looks like there's a comms issue here:

2023-01-14 11:50:41 [main] [ERROR] Unable to send telemetry:

You need to make sure all these apps are in the exceptions lists in all your firewalls:

stellaris.exe and dowser.exe (in the Steam stellaris folder)
C:/users/AppData/Local/Programs/Paradox Interactive/launcher-v2.2023.1.1/paradox launcher.exe
C:/users/AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe

If you use Windows Defender, they need to be in both the Public and Private lists there.

Good luck!

Not that I can think of, sorry - the game itself did not change this week.
 
Antivirus won't be causing communications problems. Firewalls though, often do.

Is kaspersky also your firewall?
 
Please install and run the free utility Speccy. That tells you what AV and firewall apps are active as far as Windows is concerned, and which are installed but disabled.

it says Windows Defender is disabled and under the Firewall section is Kaspersky

Okay, so you would need to make sure all those .exe files I liste din post #4 above are in all the kaspersky firewall exceptions lists. You may need help from their support on that.

Note that there may also be firewalls in your internet router/modem, and your ISP!

all of those .exe files you listed were in the "trusted" catagory, im really confused as to why its not working now, it used to before.
 
I have just completely deleted and uninstalled anything "stellaris" or "Paradox" on my computer and have done a fresh install of Stellaris, the launcher opened and was completely fine, however it stated there was an update available for it and upon restarting the launcher I got the exact same issue as before.
 
Try making a new Windows user on this machine and log into it with that. Do you get the same problem there?
 
Just wanted to ask but would there be any difference for the steam version? I have read that the launcher uses the same port as Steam, yet Steam and other games work fine. apart from having those 4 apps in the exception list what else could possibly cause this?
 
The vast majority of players of this game use the Steam edition. If all of them got this problem we'd know about it well before now!

There can also be firewalls in your internet router/modem, and your ISP. Can you connect this machine to the internet via a VPN, or failing that a mobile hotspot, and see if you still get this problem then?

it seems like this is not a game problem anymore as a free to play game has had this issue a day after installing it and now my Discord is having issues.
 
I see. I still suggest that test with a VPN or mobile hotspot!
