[basex-talk] Access to "https://raw.githubusercontent.com/BaseXdb/basex/master/basex-api/src/test/resources/first.xml" blocked?

Hi, Allthough I have never had any feedback on my R-client to BaseX, I have steadily been working on a new version (even while being retired, I still like to program :-). At present all tests are passed, except one test on adding content to a database. On my Linux-machine 'url exists("https://raw.githubusercontent.com/BaseXdb/basex/master/basex-api/src/test/re...")' returns TRUE and 'first.xml' is added to a database. When executed on a Windows machine, the same test returns FALSE. I have tested other URL's - starting with https or http - and they are all accepted. Any clue why "https://raw.githubusercontent.com/BaseXdb/basex/master/basex-api/src/test/re..." is blocked? Ben
