Lesson 3 in skill "Slang" not working

Hello, When I try to open lesson 3 in the skill slang, it doesn't work. The browser tries to load the skill for a few seconds, but then boots me out back onto the main tree page.

It is rather frustrating as this is right at the bottom of the tree. I am so close to being able to complete the Duolingo Vietnamese course, but this skill not working is preventing me. (I don't want to test out of anything.)

Has anyone else had problems with this lesson? Or did it work fine for you? Thanks

A bunch of us are running into this bug. See https://www.duolingo.com/comment/17951693 for more info. Looking at the javascript trace I’m getting a 504 gateway timeout whenever I try to access the lesson.

Can you file a bug report at https://support.duolingo.com/hc/en-us/requests/new?

Raychow1 pointed out that you can workaround this bug in the meantime by doing the later lessons at https://www.duolingo.com/skill/vi/Informal-Expressions/4 and https://www.duolingo.com/skill/vi/Informal-Expressions/5

Then if you Test Out of the Slang skill, you can get to the next skill and complete the tree.

I’m not sure if anyone’s able to actually complete the tree without this workaround.


I tried that. It didn’t work.


sorry, no I have got to this, but let this serve as a bump - and let this lingot be of worth!


Thank you! Good luck getting to the end of the tree and hopefully the skill will be fixed and working normally by the time you reach it :)


It may be a long time until I reach it as I am 17% through the tree


good luck, for vietnames
