## Request Header Too Large
|
|
|
|
|
|
|
|
|
|
The `request header too large` error with a status code of `431` indicates the HTTP request made to *Authelia* had
|
|
|
|
|
headers exceeding the server [read_buffer_size](../../configuration/miscellaneous/server.md#read_buffer_size) parameter.
|
|
|
|
|
|
|
|
|
|
Usually the defaults are sufficient however some applications cause fairly large headers to be added to requests.
|
|
|
|
|
|
|
|
|
|
It's suggested you increase the [read_buffer_size](../../configuration/miscellaneous/server.md#read_buffer_size)
|
|
|
|
|
configuration option (by either doubling or quadrupling it) in order to alleviate this issue or use the reverse proxy to
|
|
|
|
|
remove the excessive headers which are causing this issue.
|
|
|
|
|
|
|
|
|
|
It's generally recommended the [write_buffer_size](../../configuration/miscellaneous/server.md#write_buffer_size) is
|
|
|
|
|
also increased.
|
|
|
|
|

## User Has Been Inactive Too Long
|
|
|
|
|
|
|
|
|
|
An error with the text `User john has been inactive for too long` where `john` is the username indicates the user did
|
|
|
|
|
not decide to utilize the remember me option, and their session has not been used for more time than is configured in
|
|
|
|
|
the session [inactivity](../../configuration/session/introduction.md#inactivity) configuration option.
|
|
|
|
|
|
|
|
|
|
This error can safely be ignored as it is meant to be informative. You can reduce this error from occurring by adjusting
|
|
|
|
|
the session [inactivity](../../configuration/session/introduction.md#inactivity) configuration option or by having users
|
|
|
|
|
select the remember me box.
