Can't connect to site during maintenance using HTTPS

I enter in my url bar on chrome:

Url in omnibar became:

When I change the https into http:

Url in omnibar became: Roblox Maintenance

Apparently when using HTTPS, the main site doesn’t redirect me to the maintenance page.
I manually visited Roblox Maintenance and it looks the same as the HTTP version.
Visiting the site using HTTPS when under maintenance isn’t supported it seems.

(Not that big of a problem, but very confusing, I even tried ipconfig /flushdns and stuff)

EDIT: Now I suddenly get a 502 from DOSarrest while visiting
2m later: Now I do get redirected to another maintenance page.
Apparently the “no redirection during maintance on HTTPS” was only temporary?
