Official links contributions suddenly starts to get declined with no reason listed

Hello.

I have now had 3 different official links additions that are declined.
Separate dates
All with reason : "Other Your contribution has been declined.We did not capture a specific reason during processing."
All are links to the official sites for the shows at the distributor, and direct link to the shows, not general sites
- so link itself proves the contribution
Never had any problems with this before, so seems to be a fault going on?
