Problem with Flash



  • Hello,
    I use Vivaldi tile option with the Oracle Entreprise Manager 12c to monitor our main databases on Ubuntu desktop.
    (Unfortunately, Oracle Entreprise Manager 12c works only with Flash for database activity graphic...)

    I implement a script to switch each 15 minutes the screen to a new workspace.
    I have 3 Vivaldi browsers open with 6 tabs by browser.

    Since few weeks, I have a warning box appear on the each tab. I can't remove it :
    "Internal Error has occured. Check the log file for details."

    I try with Firefox and I don't have problems.

    Do you have an idea about the problem ? Where can I find the log on Ubuntu ?

    Desktop Information :
    Ubuntu 16.04.3 LTS
    kernel : 4.4.0-103-generic

    Oracle Entreprise Manager

    Did you check, if the error message comes from your servers?



  • @gwen-dragon
    It's the first place where I looked but I didn't find revelent error message.
    In the same time, Entreprise Manager is black box with hundred log fail in many places... It's not impossible I was not looking on the correct logs

    I can't open a ticket on Oracle because the problem occur only on Vivaldi.


  • Moderator

    Perhaps Oracle's software does not know there are newer Vivaldi versions.
    Lets try to fake an other browser.
    Install extension User Agent Switcher and switch the button to Firefox



  • I also test with Chromium without error.


  • Moderator

    @toto_01 Yes. Chrome often works everywhere.

    But you should try with Vivaldi by faking an other user-agent.



  • @gwen-dragon said in Problem with Flash:

    an other user-agent.

    What do you mean by that ?


  • Moderator

    A user-agent is the browser identification string sent to a webserver.

    Did you install User Agent Switcher in Vivaldi as i suggestedt for a test?



  • @gwen-dragon said in Problem with Flash:

    Sorry I didn't see you previous message.

    How can I download the extension to install on offline machine ?
    I try this method : https://superuser.com/questions/290280/how-to-download-chrome-extensions-for-installing-in-another-computer
    And I have this error : Manifest file is missing or unreadable.


  • Moderator

    Try this pelase:
    Change the useragent with Vivaldi's Developer Tools (F12)
    See https://www.technipages.com/google-chrome-change-user-agent-string
    Change UA to older Chrome version
    Do not close th Developer Tools window
    Hit F5 to reload you monitoring page

    Does this help?



  • For other user reading this post, I was not able to install extension User Agent Switcher.
    This extension cannot be install offline.



  • I temporary fix the problem.

    In place to use the url, I replaced the hostname by the IP.

    Vivaldi ask me to trust the host and that fix the problem.

    Is-it possible to always trust an host ?
    (I asked to the admin sys to change our certificat)

    By the way, I'm using Vivaldi also on my work desktop through a Proxy. It is really painful to always do this manipulation after a vivaldi update !
    https://askubuntu.com/questions/513840/google-chrome-proxy-settings

    Is-it possible to add specific fields in interface setting or/and to keep it after an update ?

    You or your admin can add a self signed certificate on your workstation and increase trust
    Add a certificate

    Vivaldi uses your local Linux account proxy settings.
