Understood!
I believe that your last statement is related to this info below:
**Nydus and Port 2224
Nydus refers to a pair of agent applications (nydus-ex and nydus-ex-api) running on your server that communicate with the server dashboard, providing resource metrics and performing server operations you've requested. The agent listens on port 2224.
Because the server dashboard and upgrades rely on Nydus, blocking port 2224 - or removing Nydus from the server - stops these features from working.
If Nydus components are removed, you need to restore from a backup that was saved before you removed those components. If you don't have such a backup file, follow the steps to rebuild the server.***

Please keep me posted about it : )
