Random short periods of offline in https outlook.office.com

Hello everyone,
I have a squid 0.4.45_3 + squidproxy 1.16.18_13 setup and running for a single interface, running as a Transparent Proxy with ACL (being all access blocked by default) and no cache.
And from times to times, I have machines, doing it randomly, giving ERR_SSL_PROTOCOL_ERROR and ERR_FAILED in browsers. I've already installed the proxy cert CA, but still I am seeing those ERR_SSL_PROTOCOL_ERROR.
I've also installed the SSL CA cert in every machine behind this proxy, in Trusted Root CA.
In squid for SSL filtering, it says that for Splice All, doesnt need to be intalled the CA certificate in below clients, who is the same interface setup for proxy. But in CA option, for SSL interception enabled, it needs a certificated there, and there is a warning, that the CA cert must be installed in each computer to avoid SSL errors. I really dont know how it must be ...
Here are the options that I have right know:
This ACL that I have is applied to this group of computers:
Firewall rules applied to thos machines behind proxy:
Sometimes by just refreshing outlook.office.com, in one machine behind the proxy, seems to solve those errors in others. I've tried with and without cache, and in edge and chrome browsers, but doesnt seem to be a browsers issue.
I really dont know what to do anymore.
Anyone here knows or have ever encountered an issue like this?
Thanks in advance!
