Hi Benjamin,
You are registered a DMR ID on June 24, 2019. I think this registration is very new and the Openpot ID database has not been updated yet so your callsign could not be found. Secondly: Your callsign is fine on YSF reflector, last letter is 'O' not the number zero. Thirdly: Looking up your callsign showed ON5BGO and "callsign not found" status at my Openspot.
