Session Mismatch on mobile phone

  • Hi, dunno if this is the right place to ask but here we are.
    I use Opera Mini for Android to surf Vivaldi forum on my mobile.
    Does not matter if I am on wifi or mobile connection I always get Session Mismatch and/or "Your lost connection" popups.
    Session mismatch send to alternative login page and login automatic.
    This happen only on Vivaldi forum.
    Can any user verify on mobile phone with chromium based browser?

    Cheers, mib

  • Can not reproduce with Opera Mini 28

    Opera Mini uses a compression server, i guess that could result in problems.

    I tested with Opera Mini 26 and 28 (both slow crap! on my old S3) and had no session problems.

  • Same here! Firefox beta.
    I get this annoying popups every time. So the Forum is almost unusable on mobile.

    It looks like your login sessions no longer active, or no longer matches with the server. Please refresh this page

  • Hi, thanks for testing.
    The problem disappears with turbo/blocker mode off.
    Should I report as bug anyway?
    I think it is not a bug in Vivaldi.
