Why is the firewall blocking the packages of an allowed application?

Question

Computer networks

The Discord messenger is launched as follows:
dicord.exe -> update.exe (it closes and the program loops on checking for updates).
Allowing rules have been created for both processes.
Successful connection log (all outgoing connections are allowed)

Steam had a similar problem. At the time of checking for updates, some blunts. The processes are the same, I do not understand.

Answer 1

When updating the application, you must assign the rules again, or disable auto-update

Answer 2

Everyone goes through the firewall.
It can be seen from the logs that the application is trying to connect to the address 104.16.58.5 on port 443 and it does not work - the firewall is blocking (another option - the server itself is not available).
It is not very clear where exactly you are watching network activity.

Answer 3

Logically, if the application starts, then the access to the network should be through it, therefore, I should see the ports

Logically, if you start the update, then the process responsible for the update is launched, which should download the update, crash the discord.exe process, unpack the update, start the discord.exe process.
Well, it’s so, purely logically, but I don’t know how you actually have it there.
