Could you let me know if it works? I am not sure if 'Searching for supplies' is the name that 'Discovering services' now has.

@ia06 Hi, did you got this error fixed, if yes, how plz ? =/

@el-espectro-0 sent you in pm

@ia06 If you could copy and paste it here I may be able to use the google translator to examine it, but I have saved some errors of mine (in my language) and the structure should be the same.

@el-espectro-0 I dont know what you need to know and its in swedish :)

@ia06 Could you show the error details?

@musicmee I think the antivirus problem would have occurred when trying to start the game that's why I ruled it out.
Forget it, I thought he was looking for supplies literally lol, I did not know it was one of the phrases on the title screen.

@el-espectro-0 Yeah I got a error on SoT, It also says that im in lobby but the game is not running.

@ia06 That used to be the common denominator in the CTDs...

Could you check the Windows event viewer to see if it mentions something I can use to help you?
Inside of Event Viewer → Windows Logs → Application

As in this picture:

@musicmee Closed the antivirus... I think i installed every app i can find :)

@El-Espectro-0 I wonder if this is the comodo thing just slightly earlier?

@ia06 Any antivirus that may be stopping the game from connecting?

You could also try install a free app from the Microsoft Store and try play the game again, that sometimes fixes these weird issues.

@el-espectro-0 No i dont.

@ia06 Do you have an amd card?
