@k WELL i cannot find any error or bad http status code in the logs since last restart, so I have no clue

@Gargron it is vertical. ffmpeg -i Qa1a2ef.mp4 -c:v libvpx -b:v 1M -c:a libvorbis lolcat00.webm Press [q] to stop, [?] for help
frame= 901 fps=9.6 q=0.0 Lsize= 2365kB time=00:00:15.01 bitrate=1290.2kbits/s
video:2358kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.291710%

welp encoding as a webm didn't help... the webM is under 2.5MB but still I get the same error https://mastodon.social/media/2004 https://mastodon.social/media/2005

@k I don't know what the issue is, most severe thing in the logs is a 422 status code. Open web inspector, switch to network tab, then try the upload again, and tell me what the actual response looks like
@Gargron SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
