Re: Fedora 29 - Interaction with TLSv1/SSLv3 completely broken

Upon further inspection it seems I am only getting this issue with github host ending in .112. Requests to 113 seem to work fine However, I am getting SSL interference via chrome with lists.fedoraproject.org as well -> https://i.imgur.com/wlU5FVE.png So now I am even more confused but of course still not ruling out the ssl decryption for packet inspection...
