Indesign 2025 stops Internet connection

[cadispraha]

Hi, my InDesign 2025 intermittently disconnects my PC from the Internet, including access to the local router. However, I can still save data to Synology LUNs, so the Ethernet connection seems to be working properly. When I shut down InDesign, the connection is immediately restored. Any ideas on what might be causing this? Thank you.

Extremely strange... 

Are you sure it's disconnecting - or just using it so much, that it looks like you don't have the Internet?

What platform and OS version? 

When have you installed InDesign / while CC? 

What is the supposed speed from your ISP - to your home / office? Is it a direct or intermediate connection?

I have three computers in the same LAN segment, remaining two is working during this troubles without any problem. And as I wrote, I can't reach router which is in the same segment. And ethernet services is working, I can save my work before Indesign shutdown, so it is some upper layer above ethernet services. And Internet is back immediatelly after ID shutdown.
I am using the latest CZ version of ID 20.2. And this happens only time to time. Let 's say I can work two three days and then Internet stops. 
W11 - the latest version including all patches - CZ version. Standard PC, nothing special.

Versions? Operating system? details?

Generally speaking, an app cannot shut down an internet connection.

yes, I thisk so, but... 🙂 
ID 20.2 CZ version, I am not fully sure but 20.0 has the same troubles. W11 - CZ - with all available patches. What kind of details do you mean?

Are you in a corporate environment? Perhaps InDesign is calling out to an Adobe service and IT is detecting the port call as a potential hack. (For example, it might be an Adobe Fonts port issue.)

[cadispraha]

no, it is two-man company with three PC, 2x Synology arrays and Fritz router, all in one segment of  LAN...

Recently, there were reports about problems with some latest updates to Windows 11 - KBxxxxxx - that should be uninstaled or repaired.
