why sometimes i cant use it, it takes very long time in 10%.
Please check Auto configuration gets stuck at 10% section first to see where this issue is from.
Then confirm that How to check the basic functionality works fine in your environment. It’s a first thing you should test.
Even if it still doesn’t work please delete Mudfish then make it sure that removed C:\Program Files (x86)\Mudfish Cloud VPN
directory then re-install it.
