My source code server has been infected ransomware and when I want connect to the VisualSVN via Tortoise SVN the following message is displayed :
VisualSVN runs without any problems and Everything(All users, Repos, Branches, Trunks and and so on) is displayed in the VisualSVN server and I can even create a new Repo But I can not connect to it via Tortoise SVN. This problem continues even after VisualSVN service restarted.
Is there a solution to this problem?
The error tells that the access to the repositories is forbidden. I guess that the virus you caught made modifications to user access rules lists or made them unavailable.
Repair your server or restore the data from backup. And don't forget to ensure that this will never happen in future.
