When trying to download the Jagex Launcher, I receive the following error:
"Failed to contact the alias service
Read operation
TLS1 error"
Since I linked my RS3 account to Jagex, I cannot log in anymore using the Runescape Launcher, but I cannot use the Jagex Launcher either, therefor I'm locked out of my own account.
I'm sorry you're having issues, have you tried to completely log out of the launcher, close it, restart, and re-open and attempt to re-log in? Also, you are logging in with your email for your Jagex account correct?
