When attempting to add a friend to my friends list, I receive the error "Error adding friend. Please try again." How do I fix this error?
If you haven't blocked them, they may have blocked you from contacting them.
If a Steam user has blocked you from contacting them, Steam Support cannot assist you in bypassing that block. Requests to do so will be denied, and tickets regarding such matters will be closed.
If your Steam account has not completed a Steam Store/in-game purchase, your account is considered a Limited User Account.
