The achievements dialog is failing to load on several sites for me. It works fine on Meta Stack Exchange and Meta Stack Overflow, but on any other site I've tried (main or meta, including main Stack Overflow) the dialog fails to load and eventually errors out with an error 500 after 21 seconds.
Left: here, right: other sites.
The same is occurring with my inbox.
It's working exactly the same way on this PC as it is on my phone, and this occurs even if I disable Privacy Badger and my userscripts.
My network tab in my developer console consistently reports the inbox request failing after 21 seconds with an error 500, and an "Oops! Something Bad Happened" page for the response:
Sites where the inbox & achievements dialogs load:
- Here on Meta Stack Exchange
- Meta Stack Overflow
Sites where I've seen they won't:
- Stack Overflow (main only)
- RPG Stack Exchange (main or meta)
- Board & Card Games Stack Exchange (main or meta)
- Arqade (main or meta)
- Game Dev Stack Exchange (main or meta)
