Hi all, I installed the server and set SSL using Let's Encrypt. I'm using Google Cloud Instances with it's LB. I'm facing now an issue where Apache is returning the following error when trying to connect: ``` Bad Request Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please. ``` checking the apache error logs I see the following: ``` [Sun Dec 17 00:12:43.395833 2017] [proxy_http:error] [pid 256] [client 10.142.0.2:39276] AH01114: HTTP: failed to make connection to backend: localhost [Sun Dec 17 00:16:42.576879 2017] [mpm_prefork:notice] [pid 43] AH00170: caught SIGWINCH, shutting down gracefully [Sun Dec 17 00:16:44.177293 2017] [mpm_prefork:notice] [pid 39] AH00163: Apache/2.4.6 (CentOS) OpenSSL/1.0.1e-fips configured -- resuming normal operations [Sun Dec 17 00:16:44.177370 2017] [core:notice] [pid 39] AH00094: Command line: '/usr/sbin/httpd -D FOREGROUND' [Sun Dec 17 00:16:46.163731 2017] [proxy:error] [pid 160] (111)Connection refused: AH00957: HTTP: attempt to connect to 127.0.0.1:8081 (localhost) failed [Sun Dec 17 00:16:46.163813 2017] [proxy:error] [pid 160] AH00959: ap_proxy_connect_backend disabling worker for (localhost) for 5s [Sun Dec 17 00:16:46.163822 2017] [proxy_http:error] [pid 160] [client 10.142.0.2:39350] AH01114: HTTP: failed to make connection to backend: localhost [Sun Dec 17 00:22:16.209422 2017] [mpm_prefork:notice] [pid 39] AH00170: caught SIGWINCH, shutting down gracefully [Sun Dec 17 00:22:49.261464 2017] [mpm_prefork:notice] [pid 2518] AH00163: Apache/2.4.6 (CentOS) OpenSSL/1.0.1e-fips configured -- resuming normal operations [Sun Dec 17 00:22:49.261542 2017] [core:notice] [pid 2518] AH00094: Command line: '/usr/sbin/httpd -D FOREGROUND' ``` Any idea what could it be?
