Hi
I can not generate letsencrypt certificate for my site. The log said :

nginx-ui[23175]: [admin.xxx] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized ::xx.xx.xx.xx: Invalid response from http://admin.xxx/.well-known/acme-challenge/a06FHfyvjHkCAa2O6w4fD0xhwesPcs_aYQOt0A2_F_c: 403

I checked and see that the port : 9180 is not listening.

Can u help?

Hi @tranthibichhlieu,
Please add this location block to your config.

Then save the config and try to obtain the certificate again.

hi, i did it but still get the same error.

As I checked, there is no process listen on port 9180, which is using for HTTP chalenger

For users having the same issue, this configuration exists as a template:

I was desperately typing manually and copying-pasting configurations from https://github.com/0xJacky/nginx-ui/issues/167 without success. Then I used the template and it just worked.
