  • I have an issue with my Opera Mini on my phone. I can't open any website on it, the only info I get is that there some kind of server certification failure and that I should check the settings of the date and time of the device. But I have an automatic setting for the date and time, And I don't know where else to check. I can't access any of the websites, but on Chrome everything works fine. Other apps use data and connect without problems. How can I fix this? and if I need to re-install Opera, can I save the sessions and all my opened tabs somehow?

  • @mychakk EDIT: I tried to reinstall the Opera Mini, but it didn't help at all, not a single website, including Opera forums opens. There is only the information about the server certificate failure. I tried both wifi, and mobile data, the same result. And hour ago everything worked fine, now nothing works on Opera mini. I tried switched off and on my phone, didn't help either.
    Does anyone have the same issue?
    What is wrong with Opera in general lately? There are also some serious issues with Windows version....

  • I'm having exactly the same problem and have also gone through the same steps. No idea what caused it or what to do. One moment everything is working fine, next all I'm getting is the same error message you have. Would love a reply to this thread so problem can be sorted

  • @mychakk Any difference if you change data savings mode?

  • @leocg I haven't tried the data saving mode at all.

    In the end I downloaded Opera for Android, and logged there and that version works fine. BUT! as I was trying to reinstall Opera Mini (before getting Opera for Android), it not only installed the app again, it also saved all my settings, speed dial, and ...all opened tabs (which was a positive surprise although I didn't know if it's suppose to work like that), but the issue with server certification was still not solved.
    So I decided to try Opera for Android, and as I was setting it up, I tried to recreate all my speed dial from Opera Mini, so I downloaded it again (once again it saved all my settings and all opened tabs), AND I noticed that the websites started working fine by then.
    So now both Opera Mini and Opera for Android works fine and I have both of them on my phone.
    I'm going to keep both apps on my phone, unless it's not advisable to do so?

  • @mychakk By default, data savings is in automatic mode.

  • @mychakk Since yesterday there is some problem the automatic data saving mode, as said by @leocg . Even today it works only sometimes, try setting data saving to off. From what I understand, data saving uses some internal Opera servers to compress and send data to the browsers, perhaps there is some problem there.

  • Thank you for your help. I'll try those tips and see how it goes.
