We're currently running the Ecency open-source build, slowly making it more sloth-like. We've moved away from the outpost for now, as it's limiting, this new build allows users to explore more of the amazing benefits Hive offers.
Please use Keychain to log in, there are no issues with keychain (and it's more secure than inputting your PKs into websites). The error is due to us using the Ecency open source build, which still 'claims ownership' hence the error message.
Thank you, I'll try it that way. Much success with your build!
