Content Filter Blocks Communication with Dataserver from Application (NinjaTrader.exe)

Content Filter Blocks Communication with Dataserver from Application (NinjaTrader.exe)

This has only been the case since this week, everything worked correctly last week. I made various attempts, disabled the software firewall (ESET) and every single Zyxel service (Content Filter - IDP - Anti-Virus). I only had to turn off the content filter and since then it's been working again, but that's not the solution for me

Attached is the activation in my SW firewall

How can I enable communication with the application again
