Bug ID: 68517
Summary: Getting AH00898: Error during SSL Handshake with
remote server while using apache as reverse proxy
Product: Apache httpd-2
Version: 2.5-HEAD
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: All
Assignee: bugs@httpd.apache.org
Reporter: sbhanwr...@gmail.com
Target Milestone: ---
We have installed apache 2.4.58 in a new directory, We use the same setting and
SSL certificate wallets as apache 2.4.57 . However, we keep getting 502 bad
gateway issue in newer apache while its working fine in apache 2.4.57 on same
server
I tried tried below settings as well, but no luck.
SSLProxyCheckPeerCN off
SSLProxyCheckPeerExpire off
I have verified by proxyCA with curl, it works fine.
I struggled with this issue for couple of weeks.
Thanks a lot,
