Panic error

[samui68400]

I encounter an error indicating that the given aggregator URL is invalid. This is strange because I successfully changed the aggregator URL earlier and didn't encounter this error when listing my accounts or attempting to mint tokens.

I also tried to add a new account, but encounter a panic with an error message indicating that there are too many requests for account registration and that I should wait until the next block is approved. This error is also due to the unapproved proposal block.
