Any ideas what this could be?

Unfortunately I can't, I have no more access to routeur, only SSH connections where allowed in the VTY lines. I'll request to reboot the router and I'll see if the connection comes back.
Thank you!

Does that router allow SNMP write access? There is no possibility of console access? After you made the change did you do copy run start?
