Authentication has stopped working. It seems to succeed on the eBay side but then when bidslammer reloads it says there was an error
My account is pre-2020 I believe. The error messages suggested raising this ticket

Hello Lionel,
Thank you for your question about your auth. I see you placed snipes recently. If this wasn't resolved, please try it again, and we can look in the log to see what the issue is.
So let us know, and if that is working ok now, then please let me know you need help with anything else.
