I've been using Opera Mini (Stable & Beta) for many years.
Somewhere between the stable-22.0.2254.113472 and stable-23.0.2254.114353 something has changed that causes a net::ERR_TOO_MANY_REDIRECTS message when visiting a secure page (https).
The older version has no problem, but the newer version will show this error message when not in extreme mode (data saving on Wi-Fi is turned on and I'm on Wi-Fi).
The same also happens between beta-23.0.2254.114097 and beta-23.0.2254.114298.
The few other browsers I've tried on mobile (Android's default browser) and desktop (Chromium and Firefox on Linux) has no problem with this page.
