Did you resolve this? Make sure the root that shows up on the certificate details page is UserTrust - if it&#x27;s not, it&#x27;s possible someone is performing MITM on you.<p>SHA-256 Fingerprint for tails.boum.org should be:<p>F8:DC:67:21:96:77:46:F5:9D:77:BD:7B:87:C1:39:42:C8:4E:4B:25:97:34:AC:E2:80:24:99:35:D9:81:9C:B6<p>If that doesn&#x27;t match the value you see in the Firefox or Chrome certificate details page, please, send as many details about the chain as you can back, I&#x27;m very interested to see what&#x27;s happening here considering you&#x27;re not on a corp network and seeing this and even moreso because this is the Tails site, something that might very much interest some attackers...
