Dear Support Team,
After I have Virtualmin Pro installed on my Linode server, it become impossible to connect to the server from China with SSH, it's only possible to connect through VPN with a non Chinese IP address.
Before installing Virtualmin Pro, I did not have any problem to connect to the server with my normal Chinese IP address, it was also fast.
I found this problem also with ownCloud installed with Virtualmin, when I try to connect to ownCloud on IOS APP with my normal Chinese IP address, it tells that it is impossible to connect to the server. But after I turn on VPN service with a non Chinese IP address, it can connect to the server instantly and everything work fine.
Is there any Virtualmin default configuration that does not permit connections from China?
How can I fix this problem?
Please help me!
Thank you in advance for your kindly help!
