Hello,
There is an issue with version 9.4.0:

Send password for Claymore API requests
field is missing in this version and can no longer connect to External Miners with PhoenixMiner installed.
Please fix this or provide download url for version 9.3.5 installer.
Thanks,
Rhino666
Thanks for the feedback. I will add back this setting in 9.4.1 that will be made available quite soon.
