Hi
After upgrade to new version of avast internet security, one of my web pages on local area (same network as PC) cannot be reached. I can ping, but no web interface. other pages on other devices is running. It looks that Firewall block some components on this web or something, but I cannot find a reason why. I try to put some expection, but did not work. Only way is to disable firewall.
please help where I must put the exception to ignore this one ip from scanning, something in newer version is make different like in previous version.

Sounds like you don’t have the bug fix for the port scanning not installed.

Make sure avast is running and set to automatically update
Reboot
Wait +/- 15 minutes
Reboot

Let us know if that solved it.

Hello,
i am using avast for the last 3 years and never had an issue before .
Now i purchased a LAN Temperature WEB Monitor that connects to my lan through Ethernet cable.
I can see the web page of this temperature monitor (KMTronic) only if i deactivate both the web shield and real site shield.
If i enable the web shield i can only see the page for 5 sec and then i get an error “Connection to LAN DS18B20 Temperature Monitor was lost.”. Then i have to reload again and see the page for another 5 sec.
I have tried :
–uninstall - reinstall (latest build 17.3.3443.0)
–add the url (http://192.168.1.88) to exclusions (general and web shield).
–disable automatic port scan detection.

This also happens when i connect from home through no-ip. If i deactivate the shields on home pc i can see the page.

how can i resolve this issue?
