I have the same recently, but I don't thinks its related to course size. Some of these courses I downloaded already once, but now updating fails... so it could be on udemy's end Ie. I downloaded 5 course yesterday with 15-20GB each, and one of the smaller ones are failing... something is weird

the actualy reponse to that 503 is

We’re having trouble reaching our servers. Try waiting a minute or two and then reload.

as i can't reproduce and no response from @Carlosx7 as well, i 'm assuming the error is now gone for him. Plus @Nightreaver thanks for the detail information, @Carlosx7 you could wait and if still the issue occurs i will check it though the error seems to be on server end and tool can't do much in that case as it relays on server response.

Nightreaver commented 4 years ago

hey oscar, that seems to be unrelated to "businessgroup". I already have "the complete guide to angluar 2" downloaded already some time ago, but recently it keeps failing and I cant get an update

I think there is a set of course affected that will fail to download. The course aws-certified-solutions-architect-associate-saa-c02 however seem to work sometimes, and return 503 other times. I suppose its udemy cloud messing up things or some CDN service.

So from 503 affected courses I have:

complete-networking-fundamentals-course-ccna-start
spring-hibernate-tutorial
nodejs-the-complete-guide
the-complete-guide-to-angular-2
aws-certified-solutions-architect-associate-saa-c02 (sometimes)

The issue lies indeed in udemy-dl itself! After checking this site: https://www.udemy.com/developers/affiliate/

I noticed that they say that page_size maximum is 100 If you check the udemydl ´_compat.py´ you can see some values are 1000 or even 10000. I changed all page_size to 100 and it works like charm now!

did you try to read the code, the big page size is there for purpose to get the entire course at once instead of requesting in chunks

No I didn't, your code doesn't make sense to me in so many different ways. So feel free to fix it your way - the solution is there
