With release of 8.1.5 I wasn’t able to upload my combatlog.txt file. It would stay at 0%. The problem wasn’t like any other problem people were describing. I tried the Discord channel, too. Then, I tried Adobe AIR and it told me the file was corrupt. Long story short, by moving the log file out of the log folder and to, e.g., desktop, it worked fine. FWIW.
