Let’s Encrypt certificate appears as a false positive threat on F-Secure Freedome VPN.
I received a report from a user of F-Secure Freedome VPN on OSX Yosemite, 10.10.5. that she cannot access my website (https://relay70.metatron.ai.) The VPN blocks the website as insecure. I reported the problem to the vendor (F-Secure) too.
On the vendor side the issue is tracked as the following:
Number: 00758968 Created: 2016-04-26 Subject: VPN identifies Let's Encrypt certificates as a threat
I wonder if other Let’s Encrypt users have similar experience or if the Internet Security Research Group can liase with F-Secure about the issue.
Thanks for your consideration,
