[ESET / Kaspersky] Any website shows a connection error on sandboxed Firefox/Edge

[0x391F]

Describe what you noticed and did

1. Add SandboxieLogon=y in [GlobalSettings] (see here to enable it from Sandboxie Plus GUI)
2. Visit any website in sandboxed Firefox/Edge
3. Firefox "PR_CONNECT_RESET_ERROR"/Edge "ERR_CONNECTION_RESET"

Now I using Sandboxie 5.56.3 and Sandboxie-Plus 1.1.3, everything is well.

v1.2.1 also has this issue. Most https websites don't load

I downgraded to v1.1.3 and everything was working. Few hours later the issue reoccurred.

After restarting a router, it works again. That's interesting

I had this issue few more times. Restarting a router didn't fix it then. Does anyone else have the issue?

I can not open any https webpage in any sandbox anymore. Tested firefox and edge. Outside of sandbox everything works. Sbie 1.2.6

That does not sound like a sbie issue, and since it seams to be related to restarting your router it very likely a router issue

Maybe it was coincidence as restarting the router does not help anymore. Every https website in any sandbox shows the errors on Firefox and Edge. The same webpages work outside of sbie.

onet.pl has mixed content. New sandbox

Eset <—>sbie issue. There was eset build update lately.

Generally eset thinks every ssl certificate is corrupt. Switching this option to: 'ask about certificate validity' allows opening webpages in sbie.

IDK how to fix it. ESET certificate is installed outside and inside sbie.
If I disable ssl scanning, enter ssl webpage, it works
