I think this might be the fix for both Windows and Mac users. Here's the video tutorial by tech How. I'll simplify it here.
Windows 1. Go to your ipv4 setting (e.g. Control Panel>Network and Internet>Network and Sharing Centre>Connection:Your internet setting>Properties>Double-click "Internet Protocol Version 4") 3. Select "Use the following DNS server addresses" 4. Change the setting to "Preferred DNS server: 8.8.8.8" and "Alternate DNS server: 8.8.4.4" 5. Click "OK" and done!
Mac 1. Go to your ipv4 setting (e.g. System Preferences>Network>Advanced...>DNS) 2. Click the "+" to add "8.8.8.8" and "8.8.4.4" to both DNS servers (and Search Domain if not working) 3. Click "OK" and done!
I had the connection timed out issue on my friend's 1.12.2 forge modded server. I was often able to load 1 frame before the "Connection Timed Out" and get disconnected (or only "Disconnected", "netty.io...ReadTimeoutException", etc) The video by tech How was for Windows but editing the dns setting also work on my macOS Big Sur 11.5.1. It took me hours to find the fix. I recommend installing the latest version of Java since I'm not sure if it's also part of the solution. Hopefully this works for whoever was having the same problem.
