Map selection screen: "Error retrieving page from server. Internal server error"

Which mod is responsible for this error message in a dialogue with red text?

Error retrieving page from server
Internal server error

Or is it a mod?

System sharing... I'll check the servers.

It's on my list to move to a new server and add searching.

It would be best to put the title of the mod in all error dialogues.

But then we wouldn't be able to blame Uber for everything.

That's a joke, son. (for the congenitally obtuse)
