RSS Feed transfer failure #124

Closed ThaChillera closed 3 years ago

ThaChillera commented 4 years ago

When trying to get your rss feed with TinyTinyRSS it fails. According to the devs there (https://community.tt-rss.org/t/dolphin-emu-atom-feed-fails/3927) this is due to a misconfiguration on your end.

Transfer closes with '18 transfer closed with 785344 bytes remaining to read'.

Reproducible with curl https://dolphin-emu.org/blog/feeds/

A few more details:

These work:

These don't work:

It's most likely to do with the locale system but I wasn't able to reproduce it after installing the website code on my system.

Edit: above Content-Length is 0 but I have the output of an another request saved where it's 785344:

Also came here to ask about this, confirming it fails for me too.

Ran it through the feed checker: https://validator.w3.org/feed/ and it shows it's not valid at https://dolphin-emu.org/blog/feeds/

I am also experiencing issues with this feed, see miniflux/v2#1026.

Dentomologist commented 3 years ago

I'm unable to reproduce this, and the last comment from the miniflux issue report also says it's working now.

leoetlino commented 3 years ago

Yes, the issue has been worked around since April 25th:

[2021-04-25 01:36:29] <delroth> so I think I know what the issue is, I'm going to disable caching for now
[2021-04-25 01:36:49] <delroth> I think the caching proxy in front of the website is caching the response to HEAD requests
[2021-04-25 01:44:28] <delroth> caching now disabled until I've got confirmation that the root cause is fixed
LiamDawe commented 3 years ago

Yeah it's been fine in Liferea for me now, still not entirely valid but it does work.
