I recently was attempting to connect to my RPi via SSH & Remote Desktop. After several failed attempts from accessing it from windows, I attempted to access it from my Android phone on the same network and everything works fine (SSH, RDP & my webserver on Apache2)
Symptoms: Putty(Windows) Error: - Network error: Permission denied
TightVNC Viewer: - An attempt was made to access a socket in a way forbidden by its access permissions.
Apache2 Webserver - Website loads on Android phone, not on windows
Some things I looked into: -Auth log does not show attempts when connecting with windows - I tried assigning a static IP address (as another thread had suggested) - Disabled Firewall/Defender - Flashed SD and reinstalled (Raspbian GNU/Linux 10 (buster) via NOOBS) - Changed settings in Raspi-config - Verified Pi is on the same network as the desktop via ifconfig - Connected the Pi via ethernet & wifi (Primarily WIFI)
I spent several hours looking this up, and the only possible solution I've found involved a virtual box with Windows XP to connect. I am mostly new to Linux and the RPi platform so any ideas in why I can connect from my android and not my desktop would be appreciated.
Note: NordVPN was running in the background and ended up being the root cause of the connection failures. Thank you all for the feedback!
