AVG Internet Security 2020 Blocking PLEX

All I had to do is go to Settings > Basic Protection > Enhanced Firewall > View Firewall Rules
on the Network Rules tab, click on More then select Add New Rule

Create the following rule 
 Firewall rule

I have ran into this multiple times.  For those that run into this, one thing that has resolved this issue for me that is not mentioned here, is to make sure the network is set to Private not public.  This can be found under settings.  If you see that the network is set to Public for the network connection, that will end up blocking the Plex communication.

AVG Internet Security 2024 Blocking PLEX

Dude, when I disable AVG, Plex works but firewall settings don't work. I solved it like this. There is a graphic with an empty button called avg firewall, it doesn't work at all.

Hello, Antony

I apologize for the inconvenience caused.
In this case, we need to change some settings in the Firewall.
Kindly refer to the below article for the changes to be made :

Also make sure the 'Internet Connection sharing mode' is checked.
Keep us posted.

Hi, 
I recently bought a new computer and reinstalled AVG Internet Security 2020. Since then my PLEX has stopped working on my iPad and Apple TV. I have discovered that the cause of this is the Enhanced Firewall. I have attempted to follow instructions given on previous posts, but unfortunately the instructions are a couple of years old and do not seem to be working. The only way I can watch media via plex is to turn off the Firewall. Please can you advise on how I can solve this issue! Thank you so much

Stay safe.
