Answer 1

Could be a Firewall.

Day 572... Still haven't slept or eaten... But I finally found the culprit: Windows Defender!

Basically, I had a firewall blocking JetBrains IDE Support chrome extension from sending data to PhpStorm through the default 127.0.0.1:63342 address.

--- Edit

Day 864... Same issue happened again, this time on Linux... But I finally found the culprit: Ubuntu Firewall!

Seriously, this happened to me again a few months later, using Linux, and it was the firewall again. Disabling the firewall solved it sudo ufw disable - If you care for the firewall and want to keep it enabled, gotta dive in deep on creating some sort of whitelist for it.
