Administrators Marcos 3,987 Posted February 16, 2021 Administrators Share Posted February 16, 2021 Please carry on as follows: - in the advanced setup -> tools -> diagnostics enable advanced protocol filtering logging - reproduce the warning - disable logging - collect logs with ESET Log Collector and upload the generated archive here.

Kings30 0 Posted February 23, 2021 Author Share Posted February 23, 2021 Sometimes not only nexus.officeapps.live.com but also odc.officeapps.live.com and nexusrules.officeapps.live.com too. Link to comment Share on other sites More sharing options...
Administrators Marcos 3,987 Posted February 24, 2021 Administrators Share Posted February 24, 2021 CERT_TRUST_IS_UNTRUSTED_ROOT and CERT_TRUST_IS_PARTIAL_CHAIN is reported. The certificate is signed by Fortinet which performs SSL inspection in your network but a valid root cert. is not installed on the client to establish trust.

Kings30 0 Posted February 25, 2021 Author Share Posted February 25, 2021 So what is the solution for this? Is there anything we can do to remove the ESET pop up everytime we open MS Office? Link to comment Share on other sites More sharing options...
Administrators Solution Marcos 3,987 Posted February 25, 2021 Administrators Solution Share Posted February 25, 2021 You must import the Fortigate root certificate to clients' trusted root CA cert. store or avoid SSL filtering by Fortigate. The root CA can be downloaded as per https://docs.fortinet.com/document/fortigate/6.0.0/cookbook/874405/downloading-the-certificate Link to comment Share on other sites More sharing options...
Kings30 0 Posted February 28, 2021 Author Share Posted February 28, 2021 Hi. Thanks. It seems to be working fine now. No Eset notifications regarding nexus.officeapps.live.com since the import of the Fortigate root certificate to clients' trusted root CA cert. store.
