Hi!

I have added to new sets to my BrickTracker and try to download the instructions, but they fail to download.
The message on the screen: Error: No instructions found on Rebrickable or Peeron.

This happens with version 1.4.0/1.4.1 (It should be 1.4.1, since I have re-downloaded the latest version, but still shows 1.4.0).
Sets tried to download:

76934
76918

To verify, I checked both sets on Rebrickable and the instructions are available.

Last succesfull download was last week with set 11511. If I try to redownload these instructions, I get the same message.
The logs do not show anything.

What could be wrong?

I literally just had this issue today too! Rebrickable must have changed something in their end, as the requests are caught in cloudflare now. Gonna take a look at it in the next couple of days. I have some ideas that needs testing.

Found the root cause. Rebrickable now puts the whole site behind a cloudflare challenge, so any automated request gets blocked before it can even find the instructions. That's why you were seeing "No instructions found on Rebrickable or Peeron" even though the instructions are clearly there when you check manually.

Since scraping rebrickable isn't reliable anymore, I found a way to pull them off LEGO's own instructions page instead. Same PDFs, just a source that isn't fighting cloudflare.

This is going out as v1.4.2 this week, a small patch release rather than waiting for the full 1.5. I tested both your sets and it should fix it for both you.

Also, since you mentioned it showing 1.4.0 instead of 1.4.1: that's a separate bug (also reported as #170). Version number just never got bumped when 1.4.1 was tagged. Fixed in the same release, so it'll show correctly this time.

Hopefully i can push the fix Wednesday or Thursday and update the docker image for latest and 1.4.2.

Ah perfect. Looking forward to the new release, but for now I fixed it by manually downloading them and adding them to my BrickTracker.
