Why cant I use my VPN, saying 

Why cant I use my VPN, saying The client doesn’t response with DHCP protocol

Please check MUDEC_00044 and MUDEC_00045 error link for workaround.

Mudfish doesn't have a manual way to disconnect from a Node but it'll does automatically after a moment.

Are you serious? Because it never disconnected and i cannot use any other node than the one that keeps connecting and this way i cannot improve anything because i cannot test different nodes to see which is the best for me. What kind of VPN does not alow you to disconnect from a node?

Could you please tell me which mudfish node it's still connection after restarting the mudfish program? If the connection is to PBE (Public Beta Environment) mudfish nodes, it doesn't affect your credits or performance in my opinion.

I am just not paying attention enough it seems.. So i was using the full VPN feature and the node does disconnect as long as the full VPN feature is disconnected. So i was able to figure it out and now i feel stupid.. Sorry

Also, you can try to pick one of Public Nodes at Setup - Program - Full VPNThey're provided by https://www.vpngate.net/
