Stopped sending stream logs

Hi everyone! My Auth0 tenant stopped to send logs via stream to Splunk around 4 days ago.
It shows as working well but no logs are sent to Splunk, even if registering more than one log per second internally in the tenant.
I already tried to stop and restart the stream, and also tried to delete and recreate the stream, but no success. No errors shown, looking like everything is ok, but no.
Any light for it?
