The Pc where I got the status.html file is a brand new PC. I just installed Windows on it, it never knew the old eset agent.
My peer certificate looks like :
Agent peer certificate with subject 'CN=Agent at *, O=, L=-, S=, C=' issued by 'CN=Autorité de certification de serveur, O=.fr, L=-, S=, C=' with serial number '0106da5451d495444b807c80b602231cefb67601' is signed with obsolete signature algorithm and it is invalid now (NodVerifyTrustResult: 42, NVT_NotTrusted, X509ChainStatus: 0x10000, X509CSF_PartialChain)
Peer certificate may be valid but can not be verified on this machine
Check time validity, revocation and presence of issuing certification authority
