No longer synching

I had this installed and running, but it stopped at some point. I uninstalled and installed without making any changes and it throws the following error:

Mar 30, 2023, 1:15:11 PM Error DNS error: http://icsUrl1
at callWithBackoff(Helpers:939:9)
at fetchSourceCalendars(Helpers:80:5)
at startSync(Code:159:21)

I verified the URL is the same as before when it was working. Not sure how to resolve.
Thanks!
