HTTPS decryption not working

[Patrick Laramée]

As soon as I enable the proxy and try to load an https site with chrome or firefox, I get this message :

Your connection is not private
Attackers might be trying to steal your information from www.google.ca (for example, passwords, messages or credit cards). 
NET::ERR_CERT_AUTHORITY_INVALID

 

I did import the generated certificate from fiddler to my cert store on Unbutu(16.04) and I imported it on Chrome as well..

I don't know what i'm doing wrong :(

Hello,

Mozilla has its own cert store. Did you import the cert there too?

Yes I tried in firefox cert store and no luck :(

That is weird. Which version of Mono and Fiddler are you using? Could you update both to latest? Also, could you check out the properties of the exported certificate? It should be SHA 256.

Trying to give as much info as possible, here's some screenshots of what chrome has to say about the certificate :
