Your browser sent a request that this server could not understand

Filed under: Linux — Tags: , , , — admin @ 4:51 pm

Well today I am facing another problem.

Got this answer on a apache behind a proxy .

400 Bad Request
Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

So .. it appear the header that is received by webserver is bigger then normal .

Solution is to increase it .

LimitRequestFieldSize 32760
LimitRequestLine 32760

Please note that is loaded from first VirtualHost.

One solution is to tested with this

curl -v -H “CustomHeader: `printf ‘1%.0s’ {1..n}`” localhost

Where n can be replace with a value of for example 20000

Well tryied everything

rm -rf /opt/eff.org    ( didn’t worked for me )

Reinstalled same problem.

The only solution was this found on a comment on github

$ unset PYTHON_INSTALL_LAYOUT
$ /opt/eff.org/certbot/venv/local/bin/pip install –upgrade certbot
$ /opt/eff.org/certbot/venv/local/bin/certbot –help
