-50 error with old itunes
So I redownloaded an older version of iTunes (12.6.3.6) onto windows 10 computer, because I wanted to browse the app store. However, whenever I try to sign in using my Apple id, I get the error "There was a temporary problem completing your request. An Unknown Error occurred (-50)."
The issue goes away if I completely remove iTunes 12.6 and install iTunes 12.10. I was able to successfully sign in with iTunes 12.10, but I don't really care, since I can't use the App store. After I had 12.10 installed, I completely uninstalled it, then reinstalled 12.6. I could see my apple id logged in on iTunes, but when I tried to download an "older" app and it asked for password verification, at which point it refused to log me in with the same error message.
I tried with iTunes 12.4 as well, and got the same problem. Is there anyone else with the same issue?
Windows, Windows 10
