Suddenly issue with Trakt.tv RSS feed from InfoService plugin (3 Viewers)

[Idro]

Hello,

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

https://trakt.tv/calendars/my/shows.atom?slurm=6dea0612138e7144e0e23e373c1f1fb6&days=7

it gets me the error that it isn't a valid feed, but until days ago it worked fine.

What could it be?

I saw there is a plugin section, can be moved there?
