A proxy error, while no proxy enabled Everything was file, but suddenly I am getting an error while trying to access default ftp service via wifi. Error: "The folder 'ftp://192.168.1.3:2121' is read only because the proxy server is not set up to allow full access"

No proxy is set up on wifi nither on my android nor windows PC.
And, I am on same network
I rebooted and cleared my phone's cache and dalvik cache via my twrp recovery and ftp started working.
