QGIS frozen when loading copc file from http url which redirects #52869

What is the bug or the crash?

I was trying to load copc file from http url which, after authentication, should redirect to object store https://swift.rc.nectar.org.au//test.mine.copc.laz. However QGIS simply got frozen when loading the request.

Steps to reproduce the issue

  1. launch QGIS Desktop
  2. open data source manager
  3. select 'add point cloud layer'
  4. pick 'Protocol: http(s), cloud, etc.'
  5. enter 'https://data-test.tern.org.au/uas/surveillance/test/test.mine.copc.laz' in 'URI'
  6. QGIS gets frozen after authentication

Additional context

  1. The file itself is ok. Tried with direct query (https:///...)
  2. The data server is ok. Tried with other copc visualizer querying that server.

Can you try with the redirected link directly?

It could be that the initial server supports range requests but the redirected does not and QGIS freezes while waiting to fetch the whole file. You could also check if there's network activity while QGIS is frozen to verify that.

Direct query with the redirected link worked.

here is the authentication if you need:

I just realized that no need to keep apikey a secret

Thanks for the credentials, really useful to verify the bug. Could you also check if the same happens with vector or raster layers behind the same server? This looks like it might not be point cloud specific...

Just tried adding a raster layer. nothing wrong with that.

Thanks! Could you also share the link to the raster file?
