Environment
GroupWise 18.1.2
Situation
GroupWise 18.1.2 FTF build # 133407 Webaccess installed on a SLES12 SP2 / OES2018 NCS cluster node, when I try to login in any browser, I get the Webaccess Login page , I put my credentials and I get an error after about 80 seconds of waiting : ######################## Error ############################################# "Bad Gateway!, The proxy server received an invalid response from an upstream server. The proxy server could not hangle the request POST /gw/webacc. Reason: Error reading from remote server If you think this is a server error, please contact the webmaster. Error 52 <GroupWise Cluster node hostname> Apache ############################################################################
Resolution
This issue has been reported to GroupWise development.
Cause
Unknown as of date of this document.
Additional Information
A packet trace was taken on the Webaccess / POA linux server with :
tcpdump -i any -s0 -w /root/trace.cap .
It revealed that the 3 way tcp/ip handshake between the Webaccess application and the GroupWise POA completed successfully and data was being transferred between the two and then a 38 second delay occurred for an unknown reason then the tcp/ip converstation continued but never completed as the browser error occurred "Error 52 Bad Gateway".
This issue was confirmed and again duplicated on a new OES2018 NCS cluster.
