Progress key expired?

[Stan Schymanski]

Dear Daniel,

While trying to run an update, I get the following error message after 
sudo apt-get update:
E: Release file for 
http://cdn.archive.progress-linux.org/packages/dists/cairon/InRelease is 
expired (invalid since 2d 20h 15min 6s). Updates for this repository 
will not be applied.

Is this a problem on the server side or on my side? Thanks for your help!

Cheers
Stan
