OAI Validation Problem

Hey guys, long time since I’ve been around here.
Since then, no problem at al in OJS.
Suddenly i got an e-mail notifying me about a problem with OAI (no modification made in OJS in the last 3 months, using 3.1.1-4 since october).
When tried to validate the OAI again, got the following error:

We received a request to validate (but not register) the following repository:
