Good evening, We’re are getting a Bad Gateway error returned when trying to upload large files through an IE browser to our webserver.
Front end is using apache proxy ( Apache/2.2.31 (Unix)) Backend is IIS 7.5 running MVC 5 code. 2 MB upload – Successfully uploaded. 60 MB upload – Bad Gateway after 449 seconds. 147 MB upload – Bad Gateway after 1090 seconds. I have turned on (settings for large file upload) SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 ProxyTimeout 1200 We are only seeing 502 errors in our logs on our end and they show it as being sent from the backend server (gww.dev.fbs.gov.bc.ca) for the large file uploads to the data/load directory. Please also note that we are doing SSL termination on the reverse proxy. All incoming traffic uses port 443 but all communication to gww.dev.fbs.fin.gov.bc.ca is sent over port 80. In error logs [Thu Oct 15 14:25:56 2020] [error] (130)Software caused connection abort: proxy: pass request body failed to <Backend server> [Thu Oct 15 14:25:56 2020] [error] proxy: pass request body failed to <Backend server> from some IP Can you point me out some directions on how to further investigate this? (or how to interpret this (130) software caused connection abort error?) Thanks and regards, Eric
