Access problems Service Node Manager

[LOVOL]

Hello everybody.
I have an MX-ONE 6.1 system and we can´t access to Service Node Manager (SNM ó MTS)
We have MP installed on the same server and we can access to MP correctly, but we can´t access to the SNM. We can see the SNM page correctly through http but when entering credentials it always shows us "You are not authorized to access MiVoice MX-One Manager" I can access to the system by ssh with this credentials but not the SNM. Any ideas about it?

Thanks
