One of our customers went live in FSM 6 update5 February 1st and for the first 2 weeks teches did not have any issue. But starting from 3rd week, they started seeing some of their mobile items were not sent to server and waiting in the wait and ready queue. If they log off and log in again, some of the waiting items get moved, but the 2nd time it tries to Sync , it does not happen.
users mobile log has following error
2/23/2021 4:35:09 PM|ERROR|GetMail|2|EXCEPTION: net_servererror, 400, Bad Request ... at IFS.FSMW.Mobile!<BaseAddress>+0xbb4d20
--- End of stack trace from previous location where exception was thrown ---
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
Looking at the Azure IIS log we see several messages that say
<Data>A potentially dangerous Request.Path value was detected from the client (:). at System.Web.HttpRequest.ValidateInputIfRequiredByConfig() at System.Web.HttpApplication.PipelineStepManager.ValidateHelper(HttpContext context) </Data>
<Data>https://XXX-fsm-prd.ifs.cloud:443/mobile/Activation/user=HTTPS:/XXXXXSTFSM.IFSCLOUD.NET/MOBILE/device=0</Data>
<Data>/mobile/Activation/user=HTTPS:/XXXXXSTFSM.IFSCLOUD.NET/MOBILE/device=0</Data>
We have ruled out, connectivity/internet issues. Also they use iOS and Window mobile and same is happening for both.
Have anyone seen this issue before?
