Bug ID: 66969 Summary: After a timeout, mod_proxy_http2 doesn't initiate a new connection immediatly Product: Apache httpd-2 Version: 2.4.57 Hardware: All OS: Linux Status: NEW Severity: major Priority: P2 Component: mod_proxy_http2 Assignee: bugs@httpd.apache.org Reporter: martin.bl...@bpm.ch Target Milestone: --- We get some 503 errors with mod_proxy_http2 and H2-proxypass after some timeout period. The problem only appears after the timeout. Instead of initiating a new connection, the apache proxy is answering with a 503 error after the timeout period. The problem appears in a webshop after 300 seconds of inactivity. After the timeout period the next request (doesn't matter which if html or other files) fails with an 503 error and we can't ourselves point the customer to the logout page (after the internal shop timeout). So the 503 error is ugly and for production webservers a blocker. This is the main part of the apache config, which leads to problems: SSLEngine on SSLProxyEngine On SSLProxyCheckPeerCN off SSLProxyCheckPeerExpire off SSLProxyCheckPeerName off ProxyPreserveHost On ProxyRequests Off ProxyPass / h2://xxxweb.customer/ ProxyTimeout 650 Sidenote: The same config with mod_proxy_http and HTTP/1.1 SSL works perfect even after the timeout period: SSLEngine on SSLProxyEngine On SSLProxyCheckPeerCN off SSLProxyCheckPeerExpire off SSLProxyCheckPeerName off ProxyRequests Off ProxyPreserveHost On ProxyPass / https://xxxweb.customer/ ProxyTimeout 650 -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org
