Hello,

If it is shown that you are blocked or banned it means that at some point there were two PCs with the same ID in Radmin VPN (most likely it was a clone of original machine). And because of our security measures  this ID was blocked. The only way to solve this issue is by re-registration.
To do this, you need to go to register
HKEY_LOCAL_MACHINE \ SOFTWARE \ Famatech \ RadminVPN \ 1.0 (for x86)
Or
HKEY_LOCAL_MACHINE \ SOFTWARE \ WOW6432Node \ Famatech \ RadminVPN \ 1.0 (for x64)
Remove IPv4 IPv6 and RID keys
Change the Alias key to the desired computer name (can not exceed 32 characters). And restart service. Actions should be taken both sides. Networks will be cleared.
Please note that if this PC is a network administrator, then administrator rights should be transferred, at least temporarily, to another PC.

Hi, thanks for asking the question, and thanks for answering!

if the ID being blocked/banned, is also the creator of the network(i.e. network admin), how can administrator rights be transferred ? And what is meant with "Actions should be taken both sides."? On both cloned pc's or on all the pc's on the network?

If the blocked account had network administrator rights, then it is impossible to return them. Create a new network. The re-registration process must be completed on both computers.
