Same issue over here Already checked the following: - Extentions/plugins: Edge, Chrome and Explorer - Antimalwarebytes - Full scan Kaspersky Total security - Kaspersky cleanup and the other tools in the suite The real problem is that Kaspersky blocks the connection and states "Program: Google Chrome" but does not provide any other information or context what is the cause of the call... It is not an interactive connection i think... On the other hand I sincerelly hope that is has nothing to do with Kaspersky configuration of secure connection or sth like that. PS: I do have two Windows 10 pc's, fully up to data, scanned etc. And both experience the same issues. Sometimes the issues apparently also results in no internet connectivity displayed in Google Chrome. Hope there is an answer following soon... Probably the cause will be indeed a good reaction/response from Kaspersky on an indeed invalid certificate. But Kaspersky should give more contextual information arround the event.
