According to statcounter.com [1] there are over 4x as many Catalina users as there are Mojave users (62% vs 14% of MacOS users), so I think it's just that the people complaining about Catalina are louder.

Anecdotally, I'm using Mojave and experienced this issue, a person I was trying to have a Zoom call with was experiencing the same issue on their Mojave.

I think there are enough comments scattered across Hacker News to safely conclude that it affected Mojave too - although it's possible the timeout behaviour / error handling is different to Catalina.
