守护程序模式下的截断或过大的响应标头

Question

我在烧瓶网站上有一个奇怪的错误。

重要：第一页（表单）正在运行，但是当我提交时，我有一个 505。

我在 StackOverflow 上尝试了一些事情 :)，但我找不到解决方案。

这里是日志：

我在 Apache 2.7 中的虚拟主机在这里：

python版本是2.7.12，我用的是“virtual env wrapper”。

wsgi 模块的版本我认为是旧的：

lrwxrwxrwx 1 root root   15 mai    3  2016 mod_wsgi.so -> mod_wsgi.so-2.7*
-rwxrwxrwx 1 root root 223K mai    3  2016 mod_wsgi.so-2.7*

wsgi 文件是“经典”，而 requirements.txt 文件：

$ cat ../requirements.txt
click==6.7
Flask==1.0.2
Flask-Assets==0.12
Flask-Caching==1.4.0
Flask-Login==0.4.1
Flask-SQLAlchemy==2.3.2
Flask-WTF==0.14.2
itsdangerous==0.24
Jinja2==2.10
MarkupSafe==1.0
pbr==5.1.1
psycopg2==2.7.5
six==1.12.0
SQLAlchemy==1.2.8
stevedore==1.30.0
webassets==0.12.1
Werkzeug==0.14.1
WTForms==2.2.1

有人可以帮助我吗？

非常感谢

这可能对其他人有用，我的问题是通过在 postgresql.conf 中停用 SSL 支持来解决的！！！：

80 ssl = off               # (change requires restart)
