Unable to refresh eBay token

Hi,

My eBay token has expired and I’m unable to refresh it, both on my existing account, but also for new accounts. Following the advice from previous topics, I believe I’ve revoked access to WP Lister (LWS Werbung GmbH?? Either way, WP Lister is not in the list of 3rd party apps), however I keep getting errors.

When trying to refresh the token on my existing account, I receive the following error:

Error in FetchToken(): EbatNs_ResponseError Object
(
    [Ack:protected] => Failure
    [Errors:protected] => Array
        (
            [0] => ErrorType Object
                (
                    [ShortMessage:protected] => 
                    [LongMessage:protected] => soap-fault: Authorisation token is hard expired.
                    [ErrorCode:protected] => 90002

                )

        )

)

When attempting to create a new account, I get the following error message, even though I’m following the correct steps:
