I just finished installing a new wireless card into my desktop because I had been using my laptop as a source of internet for my desktop through an ethernet cable so when error 42:6:3:2158 came up for me I thought it must be an issue with my wireless card regardless of the fact that I’m connected just fine to the internet and don’t have any issues connecting to other games. They could do with changing the wording of their errors because I just stumbled upon this thread after seeing that this has happened in the past before after doing a little digging. Kinda frustrated that I spent a good amount of time uninstalling and reinstalling drivers and software.
