[FL] Unknown Error

I got Unknown Error when I try to start any project. I've been running it fine for months, haven't changed anything and today all of a sudden I got this error. First of all it started showing errors when connecting to accounts, wouldn't scrape etc. After stopping the projects and starting them again I get unknown error. How do I solve this? Tried restarting VPS, tried disabling firewall - nothing helped. Any ideas?

Clear All Cookies Sessions? in the General Settings for the project
