[BUG] Get empty page after reload page with challenge

[flexstat]

What happened?

Hello, dear developers, I found this behavior, possibly a bug. I'm using bunkerweb version 1.5.5. + docker-compose.yml

I raise the configuration, go to the page with the challenge in the browser (for example, captcha or hcaptcha), the page loads and the system offers to complete the challenge, but just stay on this page for some time, for example 6 minutes and refresh this page i get empty answer.

Well, and accordingly a blank page without anything.

I see this warning in the browser console:

That page is loaded in Quirks mode. This may affect the page layout. For Standards mode use "".

How to reproduce?

You can reproduce the same error without waiting 6 - 10 minutes, for example, you can start the bunker, wait until everything is loaded, go to the host in the browser and see the challenge page, after I reloaded the bunker, I go to the challenge page and reload the page and see a blank response and a blank page, if I reload the page again then the challenge page will load correctly

Hi, I am having what I think is the same issue. I have the same behaviour, with the following logs:

https://paste.hostux.net/?b359019559166365#7FdGdy4ZvU4nG8urZjLbfWoRcFHvYyoJ6ch1TfKMWBz9

I have repeating 2024/02/13 22:35:45 [notice] 756#756: *139 [ACCESS] antibot redirect to /challenge : redirecting client to the challenge uri, client: 2a02:aa13:8241:1300:2847:b45d:3d69:77d3, server: auth.mydomain.com, request: "GET /ui/console/co.76882952b77ef725.svg HTTP/2.0", host: "auth.mydomain.com" auth.mydomain.com 2a02:aa13:8241:1300:2847:b45d:3d69:77d3 - - [13/Feb/2024:22:35:45 +0100] "GET /ui/console/co.76882952b77ef725.svg HTTP/2.0" 302 138 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:122.0) Gecko/20100101 Firefox/122.0"
And then
2024/02/13 22:35:45 [error] 756#756: *139 [HEADER] antibot:header() failed : /usr/share/bunkerweb/core/antibot/antibot.lua:109: attempt to concatenate field 'nonce_style' (a nil value), client: 2a02:aa13:8241:1300:2847:b45d:3d69:77d3, server: auth.mydomain.com, request: "GET /challenge HTTP/2.0", host: "auth.mydomain.com"

I don't get why antibot would interfere with my service.
Thanks in advance for any answer
