TortoiseSVN: authentication error

I have been getting:

Unable to connect to a repository at URL 'xxx'Error running context: An error occurred during authentication

I've tried clearing cache, authentication data. Tried svn info --username xxx --password xxx --no-auth-cache from cmd. Tried deleting roaming/subversion, roaming/TortoiseSvn, local/TortoiseSVN, deleteing TortoiseSVN in registry and reinstalling tortoiseSVN. But still the same error. Though i can access the repo from be browser. Any ideas?
