Bug ID: 384929 Summary: Detect captive portals Product: Akonadi Version: 5.5.1 Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: DAV Resource Assignee: kdepim-b...@kde.org Reporter: k...@sedrubal.de Target Milestone: --- Created attachment 107933 --> https://bugs.kde.org/attachment.cgi?id=107933&action=edit The certificate warning Akonadi should not try to sync with external servers (in my case the DAV resource) when the device is connected to a captive portal. If you configured to use a TLS secured connection, you'll receive many (!) certificate warnings if the captive portal web site is also available on a TLS connection and if your requests will be redirected to the captive portal website. Maybe you can use NetworkManager to determine if you are in an captive portal: $ nmcli networking connectivity check -- You are receiving this mail because: You are watching all bug changes.
