Hi @lumenav , Thanks for the bug report and filling out the tamplate :D This is because Qwant is sometimes blocking my IP for a day or so because of too many requests from my instance to their server. There are a lot of those issues already in this repo you can see another one here: https://github.com/paulgoio/searxng/issues/24 .

The only real way to fix this is to use a proxy with multiple public IP addresses... I will keep this open to track my progress on this, but this will take some time (could be multiple weeks). Keep in mind that this error does not do anything... The results still work as good as before (just without qwant sometimes)...

also from another qwant bug: we should impl. to only send searches with at least 1 char in q as a TODO:

Error

    Error: searx.exceptions.SearxEngineAPIException
    Percentage: 0
    Parameters: ('API error::q must be longer than or equal to 1 characters',)
    File name: searx/engines/qwant.py:123
    Function: response
    Code: raise SearxEngineAPIException('API error::' + msg)

After a long time I finally set up a set of http proxy server; Since the search traffic to the engines is now split between multiple public IPs, my instance should not get IP blocked for the foreseeable future :tada: ; Closing.
