Hi there, yes I discovered this issue yesterday and it is actually due to a problem with ephys/mc-curseforge-updateJSONURL. I've reached out to the developer for a resolution, but if I don't hear back I will be updating to another service for update checks. I will update this issue when I know more.

I've updated Iceberg with a workaround that fixes update checking for all my mods. Enjoy! 😄
