Tell HN: ProtonVPN is awful
And, there is virtually no support even for paid plans. After sending reports of connectivity and authentication issues, log files, and more, their "support" department is totally unresponsive nor helpful.
Since the service was upvoted heavily here, I wanted to caution anyone thinking about trying it, since there is also no trial period.
EDIT: Correction, I did receive one email response after a week instructing that in regards to intermittent authentication issues to "check your username and password" although the service authenticates successfully around 50-ish% of the time.
