Issue/Introduction

Repeated "Server connection lost, trying to reconnect messages and AWI freezes while opening objects. 

WPsrv_log_001_00 shows repeated messages like below 

U00003413 Socket call 'recv' returned error code '111'.
20220211/124234.063 -          Connection refused

 Trying to move a folder in the GUI, it freezes and loses connection.

Resolution

In this particular case we found Application Firewall (WAF) was blocking traffic it saw as attack signatures. For example it was flagging certain traffic as potential cross site scripting and then blocking it. These were false positives though and we were able to tune our WAF to stop blocking normal application traffic and  AWI starting working normal and socket call error messages from WPsrv log disappeared.
