NGINX error while reading response header from upstream

[M@rch0n]

Hi,

After updating my OPNsense to the latest version, NGinx with the error:
 
Errors*1 upstream timed out (60: Operation timed out) while reading response header from upstream


I found this help -> https://ma.ttias.be/nginx-proxy-upstream-sent-big-header-reading-response-header-upstream/#:~:text=If%20the%20HTTP%20headers%20contain,configurations%20to%20your%20location%20block..

I changed the buffer option, but other errors occur and the service does not start.

This error in the > Services > Nginx > Logs > Global Error:
proxy_busy_buffers_size" must be smaller than the size of all "proxy_buffers" minus one buffer in /usr/local/etc/nginx/nginx.conf:656

Any configuration suggestions?

Cump.

M@rch0n,

I have exactly the same problem using the NGINX proxy.
Without NGINX, no errors appear.

Did you ever find a solution?

Found the setting, in case anyone needs it.

HTTP(s) Location – advanced settings – Advanced Proxy options – proxy Read timeout = 999999
