I have searched for ages on how to fix the issue of the "Invalid signature for profile key" error, I even looked on here, its been made into duplicates saying the issue is resolved but doesn't say how it was resolved or the method to resolve it!

I've tried changing my time from automatic to manual then back to auto, I've made sure all my timing settings are right, I've made sure my firewall is not blocking anything HOW DO I FIX THIS!
