Yggtorrent Issue : invalid username or password


I have one Issue with yggtorrent provider. in the log I Have this error message :
SEARCHQUEUE-BACKLOG-306719::[Yggtorrent]::Invalid username or password. Check your settings

I am sure it the right username and password, i Tryed some times directly on the website and it works well. how i can resolve that?

And another question i have actually only one indexer the tvdb and
i tested a fork of sickrage before sickrage and it had 2 indexer and I had more result thant sickrage. Would it possible to add one more manually ?

Thank you by advance for your help.
