since a few days, kontact (version 4.14.2, missing in the dropdown menu) keeps bugging me because of an invalid certificate for easylist-downloads.adblockplus.org. the adblocker in kmail is turned off, therefore i don't know why kontact is trying to reach out for that domain anyway. i don't see this on all of my machines. tried to reinstall the ca-certificates package, had no effect.
Could you provide screeshot about this error message ?
This bug has never been confirmed for a Kontact version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12; preferably much more recent), please open a new one unless it already exists. Thank you for all your input.
