Hello everyboy,
First sorry for my poor english.

I configure a reverse proxy with nginx 1.18, it's ok.
I tried to obtain ssl with certbot, it's not ok :-(
i create a file 1234.txt on the reverse proxy to test the access.
I can access to https://[mysite]/.well-known/acme-challenge/1234.txt
but i obtain an 404 erro when it tried to access to http://[mysite]/.well-known/acme-challenge/1234.txt

where i do a mistac in my conf file?

Thanks a lot for help.

Regards,

Good morning,
It's OK all works with the new conf file
Regards
