Please carry on as follows:
- enable advanced protocol filtering logging in the adv. setup -> tools -> diagnostics
- reproduce the issue
- disable logging
- collect logs with ESET Log Collector and upload the generated archive here.

We'll check the validity of Google's certificate and report it to them, if invalid.

When testing, I received a valid certificate:

Marcos the date of the certificate is controlled by the CA non ? the entity who issues the certification and I dont see any Eset ssl filter in your certificate

My understanding is that you have Sophos in the network which filters SSL communication to perform inspection. The cert. issued by Sophos already expired. The certificate we use to sign filtered communication uses the same validity period as that set for the certificate used in the original communication:

That said, the question is why Sophos encrypts the communication with an expired certificate given that Google provides as valid one as shown in my previous post.
