Patch 5.0.8 went live 19 October 2021. Since that date DSR was unable to parse freshly uploaded replays, a week in total. Now replay parsing code is updated, DSR should work again.
If you have some of your replays missing on site, you may try removing dsr_uploader/src/old_replays.json file in your dsr_uploader, it will force uploader to re-upload your replays to the server, fixing the issue. Keep in mind parsing replays takes time, about 5 seconds per replay on average.
I am sorry for inconvenience, if you have any questions please go to discord.
