I recompiled OpenSSL to make s_server -www return the correct, static XML blob for a .NET application that was buggy to make a reproducer for them that didn't rely on our product at all and which could be self-contained on a very barren windows VM they could play with to their heart's content and which didn't even care about the network because everything was connecting via loopback, so they couldn't blame that, eitehr.
Turns out there was a known bug in Microsoft schannel that had yet to be patched and they'd wasted weeks of our effort by not searching their own bug tracker properly.
Why would they do that when they could waste your time instead?
Searching bug trackers has always been problematic unless you have an exact error message or code. Fortunately vendors like Linear are now embedding AI/LLM technology into their products, which helps a lot with fuzzy searching and with retroactively finding duplicate bug reports.
I hate that so much. It's everywhere. An example is a bug with discord. They wanted me to restart my phone, reinstall the app, what are my versions, what phone am I on, what settings, etc. After all of that they go "oh that's a known issue." Whyyyyyyyyyyy. I get that multiple things can have the same symptom, but maybe start with that. Not like I signed any NDA so they aren't hiding it's an issue from the public.
