Bad Gateway error from nginx for every thread past a certain size.

[LastTrainsEast]

Almost certainly adjustable (note the nginx). Perhaps a maximum file size.

As a workaround you can go to settings - talk settings and change ALL to 100 posts. Though if like me you're going up and down the thread reading and quoting it's not very useful that way in the long run.

I also find this an annoyance - I wish we could set the 100 limit on a thread by thread basis so that the odd thread which fills up with long posts can be treated as an exception, not require a change to site wide settings.

That would be a good idea as apparently it isn't every long thread. Not the number of posts but total size.

Perhaps they can make an adjustment.

Googling nginx bad gateway on large pages suggests a number of simple settings changes
