Suddenly issue with RSS feed from MediaPortal

Hello,

for a few days I get an error within Mediaportal when I put the RSS link to trakt calendar.
If I insert the link into InfoService plugin of MediaPortal and click Save, I get this:

I didn’t change anything, suddenly it happens, until some days ago it worked all fine.
What could it be?

Checking the log I have this message:

Remote server error: (403). Not permitted.

No help for this? It seems trakt refuses connection.
I tried to renew the access with trakt from HTPC, but I didn’t resolve.

The url itself seems to work fine. Even I can see your RSS feed without credentials. Maybe they are blocking HTPC itself for some reason
If you need personal support it’s best to send a mail to support@trakt.tv or a DM to @support

Ok, thank you. I’ll proceed as you suggested.
