waf_captcha parameter 'max_fails' option 'refreshes/tries' appears to always be 20

thank-you for some great software that allows us to serve captchas as necessary.

when using the parameter 'max_fails' for waf_captcha, it appears that the 'refreshes/tries' option is always 20, regardless of the value i use. the 'time' option changes per the value i use and works as expected:

waf_captcha on prov=hCaptcha secret=xxx file=/opt/xxx/hCaptcha_english.html max_fails=20:60m zone=waf:captcha;

is working the same for me as:

waf_captcha on prov=hCaptcha secret=xxx file=/opt/xxx/hCaptcha_english.html max_fails=3:60m zone=waf:captcha;

txs again

Did you use nginx -s reload to try the new max_fails parameters? Since the nginx -s reload keeps the original content of shared memory, the old counter will not be reset after reloading.

Could you try nginx -s stop?

i normally use systemctl restart nginx.

i just tried:

nginx -s stop
systemctl start nginx

with the same result.
