See below. The exact same file from the same server gets truncated when downloaded through https:
[admin@MikroTik] /file> /tool fetch url="https://webserver/test"
status: finished
[admin@MikroTik] /file> print where name=test
NAME TYPE SIZE CREATION-TIME
0 test file 4096 jan/01/1970 16:32:33
[admin@MikroTik] /file> remove test
[admin@MikroTik] /file> /tool fetch url="http://webserver/test"
status: finished
[admin@MikroTik] /file> print where name=test
NAME TYPE SIZE CREATION-TIME
0 test file 5.7KiB jan/01/1970 16:32:49
[admin@MikroTik] /file> remove test
This makes some automation tasks pretty difficult. Tested on 6.27 and 6.28rc20.
Please fix!!!
