@stoodkev, look here:
16:39 I created account. It is saved in blockchain.
16:45 I couldn't log in to Hive Keychain.
As you can see there is not a typo in the username.
And it was possible to log in on Ecency.
However, this has happened to us several times and is very annoying.
Yeah, I said I guessed a typo was not the reason in this case =)
It is most likely an RPC issue because as I mentioned, this error comes directly from the RPC not finding the account. I cannot reproduce the issue on my side, but ill still try to think of a way to improve the experience at this level.
Thanks for the report!
Good news, I found the issue, it was happening when a whitespace was copy pasted along with the username, causing the blockchain not to recognize it. I fixed it in 2.2.7
